alright i bought a cam specs are below.


It is having a hard time ideling


I got 24 pound injectors,

Any ideas, i've checked vaccum leaks and i'm not getting any codes throwen, any input would be great. thanks.

 

where do you see specs????

 

i didnt see any cam specs, but ill give you my , my fuel pump relay just took a dump, so i did some nice re-wiring and gave my fuel pump that "hot wire" trick and now if my 02 sensor isent heated up and reading, im geting some much more flow/psi from my fuel pump my car wount idle, but when the 02 gets up to temp it will idle at 600 rpm, will you car idle when you give it some gas peddel? because with out pcm work i think the 24 lbs injectors are flooding you car

 

How about a little more info on the motor. Timing can cause incorrect idle.

 

have you re-set minimum idle? then re-set the TPS sensor? if not, it's not gonna idle w/ a decent cam...(I'm saying decnt because I'm guessing its bigger than stock...what specs?)

 

its a 1986 305 with 24 lbs injectors. the timeing right now is set at 7 degrees. anything else?...1.5 rockers...SLP runners which are ported along with the upper and lower intake.

 

there is a custom chip in the car, and i dont' know what the hell its about b/c i didn't get it. It was the owner before me that got the chip. B/c if i unplug the O2, i wouldn't get a service light.

I've gotten in to run, enough to break the cam in and drive it aroudn the block, but i have to keep my foot on the gas, even if its just a little b/c the sec it goes below a grand it dies.

Oh and when I did take it aroudn the block, when it was floored 1st was ok, 2nd was a dog and in 3 gear it just stayied at 5,000 and didn't move much, not enought to shift into 4th gear....( i have a very long block) Which leds me to beleive that I'm not getting enough gas and higher RPMs or that my heads just can't flow with the cam.

All in all i really don't know where to start besides just pushing it down a hill and claiming it on insureance.

So any input where be great....THANKS


Oh and the injectors where on the car before i did the cam swap, and the car ran find.

 

that doesnt really say 282, 292 duration does it

 

Check to see that you got all the plug wires back in the right place. Also, you may have over tightened the rocker arms when adjusting the lash/preload.

 

Are you useing stock TPI on it ? Stock heads ? What are they ? That would be a big cam for a stock TPI setup

 

Thats advertised duration... The duration at 0.050" is what to look at..

 

I've ran that exact cam before, not TPI though.- Seems every manufacturer makes somethign either identical or really close to those specs... Yeah duration @ 050 is 224/234, kinda large for a TPI intake, but w/ the runners and the port work it should be alright. As for the run issue, have you checked your plugs? You've gotta figure out whether you're getting to much fuel or not enough. Start out looking at basics:

- you set timing w/ the EST disconnected right?
- ALL grounds are hooked back up, tight/good connection.
- Set minimum idle
- set TPS voltage @ idle
- also, "previous owner" custom chips scare me, do you have the stocker to try? (not neccessarily bad, but questionable...)

- if you can unplug the O2 and it doesn't effect how it runs, I would say it isn't going into closed loop.

 

thanks for all the help/tips, i have to work most of the day light and I this weekend is superbowl weekend so I don't think i'll be able to try the tips untill next weekend. I'll back to you guys.... once again thanks for the inputs

 

speaking of chips, where i would i go to get one burned, is there a website that i could order one from or something????
