Ok guys i have asked fdor help b4 and all of you helped me very much I will try my hardest to explain what my problems are.... First off lets start with the car idling very badly everytime i run the car i have to baby to throttle at stops to keep it going and sometime i dont have to touch the throttle and sometimes it stalls if i dont touch the gas... I just replaced the Fuel pump,strainer, and upgraded to a BBK fuel pressure regulater and all NEW accel 8.8 plug wires and accel cap and rotor( old ones were really really bad) I have also replaces the MAF, coil,tested the tps for .54 volts(dead on) I have checked the timing and its around 6 to 10 and runs kinda strong. I had it at the strip on saturday and it ran a consistaint 15.21 in the quarter mile and i have a but ton of bolt ons and it should really run faster but ever since i took it camping a couiple weeks ago it hasnt ran the same.... If you need any more information please let me know and i will let you know....Also one more thing that might help is if i dump the clutch at about 4800 rpms it will launch great and about 10 feet later it falls on its face and rpms drop and start to climb back up slowly almost like i let off the throttle(but I dont)... WHAT COULD IT BE let me know and I will try anything to get this thing running better.
Thanx Guys

 

another thing that might help is when i was repalceing the sparkplug wires on the passenger side under the sparkplugs there is a ONE wire Sensor that isnt hooked up( the sensor end is broken and I dont know what sensor this is so I cant replace it Please help let me know what it is and do I need it?

 

That's your knock sensor. Not sure if that's your problem but definately fix it anyway. Sounds like you've already replaced a ton of parts but two things that come to mind are fuel injectors and ignition module.

 

alright i went to the parts store and picked up a ignition module but due to weather i am unable to install it right now but when i do i will let you know.....One more thing that might help is that when the car is running you can feel the fuel rail and it make a ticking or clicking noise... i just noticed it the last few times i drove it and opened the hood....PLEASE PLEASE HELP

 

possibly a stuck lifter, or an exhaust leak at the header??

 

Noise could be a lifter or a loud injector. Could also be a broken valvespring...seen that happen before and the owner was driving it with it broken.

The idle issue sounds like the IAC may not be set properly. Do you have access to a scan tool? What are the IAC counts at idle cold/hot?

Need more info to narrow down the possibilities of power loss under load. Sounds like a fuel issue. How much fuel is in the tank when you are launching? You might be pulling the fuel away from the sump (a problem with some cars if you have an unbaffled tank). I switched to an LT1 style intank pump that keeps the pump submerged and it fixed my issues with fuel starvation.

 

if its the knock sensor your timing may not be adjusting 100% correct....so that could cause a problem

 

If you're running the original injectors that probably what the ticking noise is coming from. Mine got loud as hell before I finally broke down and replaced them. Try listening to each injector through a screwdriver and a bet you'll find the source of your ticking.

 

well im on my way out to install the ignition module and I will let you know how it goes....As for the ticking noise it is for sure the fuel rail and nothing else if you put a screwdriver up to them you can hear and feel the sounds clear as day.....I am also going to check the timing again but im unsure what it should be set at....As far as i know the contents of the inside of the motor are stock....I have looked a few different places and cant really get a for sure answer...Please guys i really need help....Also should i reset the computer aftrer i install the ignition module...

 

ok guys installed the new ignition module and found a few more things that might make it run a little different...The pickup and fingers where really really rusty so i took them off and cleaned them up really good...I tried to gap the pickup but there is a alignment pin underneath that wont allow me to gap it at .010 but its really close... I also found out that its not the stock distrubter its a aftermarket one thats all aluminum.... I also found out that its not the knock sensor that was unpluged it the other sensor on the pass side right under the headers that was unpluged...Im thinking it has something to do with the fans because my fans dont come on at all....Also as for the fuel rail making noise it took a screwdriver and tested the valve covers and fuel rail and its for sure the fuel rail making all the noise... I have to pickup a fuel pressure tester and test my fuel pressure with the new BBK fuel pressure regulater installed..I took it for a ride and it seems to idle a little better but it still has a miss to it it moves between 600 to 1000 rpms back and forth but now my air -fuel gauge is reading stoich more then ever b4 but it still drops when i apply alot of throttle.... I am checking on some new injectors but i need to know if i should get bigger then stock ones to help with all the upgrades... i have a few more upgrades that i plan on doing but not right away... One of my upgrades include a built 383 stroker by next summer but i would like to figure out my problem b4 i get a new motor... Please guys help me

 

You can probably get away with slightly larger than stock injectors but if you go much bigger you'll need to get a custom PROM burned. The computer is designed to run 19 lb./hr injectors so if you put larger injectors in the car the computer doesn't know that. It may cause it to run extremely rich. That said, I doubt your going to be able to use your 305 injectors in a 383. I bought a set of Bosch III injectors from South Bay Injectors and I'm very happy with them.

 

ok i am going to jump into some new injectors i really dont know what else it could be.... it does run better but still has a miss and I dont like the noise comeing out of the fuel rail.... I am looking into some new injectors but need to know if i need 17lb or 19lb injectors I am on my way to try to find out what i need but if you could let me know as soon as possible so i can get them.... one other question is when i get new injectors do i need new o rings if so can i get them from the parts store?

 

You need 19lb. injectors and yes you will need new O-rings. If you buy them from South Bay they come with them. If you go with the Bosch IIIs South Bay also includes their special adapter so they are a direct fit. The only thing you should need from the parts store is a new set of Fel-Pros for the plenum and runners. O'reillys sell the whole kit for $12. You might also want to pick up a can or two of carb cleaner. An injector swap it the perfect time to clean up your intake since you'll have the plenum and runners off anyway. The swap is fairly straight forward but this might help you: https://www.thirdgen.org/injectorswap.

 

i went on southbays website and looked at some of there stuff but i was wondering if there better then the injectors off ebay...I can get a full set of new ones off ebay for about $120 i dont really want to worry about the brand too much but if no one has tried the eaby ones then ill prolly just get them from southbay.....The car still has a funny miss and i have checked alot of stuff and replaced a ton of stuff and still has it....I have a buddy that has a data loger and he ordered a cable so he can track my performance and then hes waiting for his software so he can change whatever the problems are. if anyone else can think of anything else please let e know i can check it out....
Thanx John

 

comr on guys i know someone out there knows my problem let me know anything.... I prolly will try it...I have new accel plugs that i have to wait till weather breaks and i will put them in and hope that could be some of the problem.... I am going to talk to bbk and edolbrok and see if it could have some thing to do with there intake and throttle body and c what kind of information i can get from them....As for fuel injectors please help... am i safe with the ones off ebay or should i get them off another site... the ones im looking at are new..... please i need mad help...

 

What brand are the injectors you're looking at on ebay? If they really are new for $120 that sounds kind of sketchy to me, too good to be true. I bought a set of refurbished Bosch IIIs from southbay and have been very happy. If you call them they have a lot more than is listed on their website and they might be willing to match competitors prices if you're persuasive enough. I would be a little leary of the ebay deal myself but its your money.

 

sorry about the confusion i looked t the auction again and they are refurbished bosch flow matched injectors... Here is the item number for them. 270588710415 The seller has excellent feedback...Let me know right away so i can get them ordered.

 

I am on southbays website right now and just call ed them last night and they said they would run about $160 for 19lb injectors.... I also talked to the guy off ebay and he guarantees these are just as good as southbays and he stands be hind them 100%....I am ordering them today and hope to have them by the end of the week and installed by the middle of next week... Ill let you guys know as soon as i get them in.... Also where can i get a gasket kit for the high flow edilbrock intake????

 

Ok guys I got the New injectors in and it does run a little bit better but Still has the funny idle....The injectors that came out didnt look nothing like the ones i put in... have to get a fuel pressure tester and ill let you all know

 

Ok guys.... I think this thread is dying but i did get a fuel pressure tester and I was only running 37psi so i turned up the bbk regulator to about 50psi at 3000 rpms.... Holds pressure great doesnt loose none.... I went thru and reset the iac and tps and no it idles about 1100 and runs much better...But still doesnt seem like it runs perfect... I got a engine light and tested it and it says MAF/MAP low voltage and I jsut replaced it less then a month ago... is there something i can do to fix it.....
