when i first start the car it runs for about 5 sec then dies i start it again then runs great could it be a sensor
or is it the hypo engine lol

 

Sounds like a sensor glitch to me...any Check Engine lights? Is this your only problem or are there others, such as rough idling, funny smells, bad acceleration, blah blah blah etc etc etc..

 

Does the idle hunt around before it dies also? Mine's done it a few times in the past few days...couldnt tell you the cause..my best guess was a slightly leaking vacuum line that I had removed & unsuccessfully plugged at the manifold...

 

I am sure you do have some cold start problems as your 3.5 Interpid motor is blown.

Anyway, It is probably a vaccum leak, or maybe in need of a tune-up. But most likely something little. If the car dies, then starts right back up, maybe the intial prime from the Fuel pump isn't quite enough.

But like you said it starts right up the second time. So I am sure it is something very small. Unless the problem starts to get a lot worse, I would not spend too much on tryin to find the solution.

 

Can't sweat the small stuff! I've thrown all this money into my car trying to figure out the cause of my rough idle..and today my starter died. I STILL have a rough idle.. Point being..save the money away from the little things, cause sooner or later a big thing is gonna come along and you'll wish you had the money you wasted on the little things!

 

ya well i was b,s in bout the 3.5 any way my car doesent hunt for idle just starts revs up then dies
i thinke it could be vacume line because all the lines are all original is that bad it has 252km on original motor andf trans

thanks for the info

 

252 000 km, sounds like your from Canada, Good old metric system.
Where abouts in canada are you?

 

Do a once-over all your vacuum lines..look for brittle, cracked, or split areas on them, particularly around the area where they slide on, and where the come near heat sources

 

i live in bramton where u from \
i'll have to check lines after i fix f*uckin snow blower the belts snaped don't ya just love snow Any ways i gotta install jbl 6x9 that i got at best buy for 30$$ so i guess the cold start will have to wait



merry christmas every one

 

Nova Scotia, as it says under my avator.

 

Im having cold start problems too, my service engine light is on, i read the ECM trouble code out and it came up as a short in the fuel pump or not enough voltage or somthing, then when it does start up it sounds runs greatm but smells rich when you stand behind it, kind of like the smell down at the drag strip with all the non street cars. anyone know what my problem is, my fuel pump is all good we replaced all the stuff for it. thanks guys

 

Does it run rich only cold? Or warm too? If you're running rich, and your O2 sensor works properly, it should trip an SES light for rich exhaust as well... Just a small tangent there..

 

it varies its usualy always rich, but just when its cold its really bad like to the point where you cant even stand back there with it on.

 

Damn....well if your O2 sensor used to work, all that exhaust probably burned it out. What kinda engine and what year is your car?

 

92 RS 2.8L twin turbo

 

I'm not even going to comment on that one.................

 

why cant you help me out if you know what your talking about, im a 16 year old kid and im only used to workin on old cars, i have a LS1, T56, new drive shaft and posi rear im putting in, but i need this thing to last untill the end of the school year so i can take it off the road.

 

well nevermind you guys can suspend me do what you want, but all i have to say is you guys are a bunch of jerkoffs in this place, every time i slip and i say somthing wrong like i get an option wrong with a year, you guys flip, you think i should know every single thing about my car, i try, i have a 55 chevy i built when i was 14 by myself, you wanna talk **** on me- come to NJ and race that. suspend me do what you want you guys are ****ing jerkoffs

 

Tell us how you really feel.

First, there was no 2.8L offered in a '92 thirdgen.

Second, NOBODY here believes that you have a twin turbo without showing proof. Guys come in here all the time claiming turbo this, and supercharger that but nobody does it. Show proof or lose all credibility. Why would you spend all the money to twin turbo a "2.8" only to put an LS1 in it? Money sure can buy you alot of stuff but brains definitely isn't on the list.

Third, How the hell do you expect us to diagnose a "twin turbo 2.8"???

 

Someone had to say it...and I didn't feel like being the one this time around!
