Hey guys,
i just joined the forum and i've just bought my first Camaro today. the car is a 1988 iroc z with a 305, i think, (the previous owner told me 350) with a paxton supercharger (sn2000) on it. it ran ok today (meaning it actually drove) but it definatly has ignition timing issues. i parked it out back and did a simple fluids check and now it won't stay running. i can get it started and keep my foot on the gas and it'll idle until i remove my foot and then it stalls. has this happend to anyone else? where should i even start when looking for the problem?
any help is appreciated,
kevin
Re: new here and new to camaros. need A LOT of help
Engine code - E - should be the 305TBI which you said, NOT A 305TBI....... Could be the TPS, IAC, ECM, ECT... ECT... If it was a 305TBI, maybe! This engine is outta my league...... looks TPI >> Post there.
Re: new here and new to camaros. need A LOT of help
thanks, i've got it running again. i cleaned the IAC off with some electrical parts cleaner and it started up again. i talked to a mechanic buddy of mine and he told me to start with the IAC.
Re: new here and new to camaros. need A LOT of help
good start, check the knock sensor, o2 sensor, timing and of course ur plugs. on a newly purchased car, i always do a tune up, even if they say it was done 2 hours b4 i pick up the car. at least check it all, then you know whats good to keep and what can be replaced.

Re: new here and new to camaros. need A LOT of help
welcome aboard! That's one heck of a setup to start with in your first 3rd gen. As someone mentioned, that VIN code denotes a 305 TBI motor originally came in the car. However, since you've got a tpi intake on that motor (along with a nice whistle), you may very well have a 350. You should be able to learn a bit more about the motor by running the engine and head casting numbers through www.mortec.com
Re: new here and new to camaros. need A LOT of help
from what you have described-do a compression check. i think that you are hearing knock when you say "ignition timing issues." get a ballpark idea of the basic condition of your motor. remember start with basics.

Re: new here and new to camaros. need A LOT of help
thanks a lot guys, i put a scan tool on it today at school (i retract my previous statement about pulling codes haha) and i pulled 4 of them: coolant sensor (which i had unplugged and is now back in), throttle body heater (i can't remember the exact wording of it), o2 sensor too rich/too lean, and the last one has slipped my mind as of right now. when i had to put the engine code, from the VIN, into the scan tool i had to use "F" which came up as 5.0 TPI and the computer was able to comunicate with the scan tool. my question is can you use a 5.0 tpi computer with a 350 tpi? or do they use the same computer or what? this is my first GM product in a long time so i'm sorry if it seems like i'm asking a lot of simple questions here.
