Im having problems with my IROC right now.. it shakes when i give it gas or when im driving for that matter and i dont know whats wrong with it.. it was fine the other day when i had it out and its been like this for the past few days.

Any ideas?

thx

 

did you do any recent work on it? if the shake is always there check the driveshaft. is the car shaking or is the motor shaking the car, might be missing. something to look at

 

yea i had some exhaust work last wednesday. and sometimes it doesnt do it but it will just start all of a sudden

 

Is it running poorly?

 

when it shakes yea it runs poorly, but i can hear it in the exhaust, it sounds choppy when it gets shaky

 

I was going to say check you plug wires, mine was missing and studdering when acelerating, if that doesnt help chances are its the plugs.

 

yea the plugs are pretty old, i never did change them after it sat for a couple years

 

i was just talking to a mechanic i know and he said i should get an injector flush and if that doesnt work he said i prolly need new injectors.. how much does it cost?

 

The plugs are probaly the problem, injector flush? never heard of that, nothing alittle sea foam or injector cleaner cant fix.

 

Plugs are good, and injector cleaner didnt do it.
when it gets shaky like that the needle on the tac skips when it hits about 2500 -3500 rpm

 

Plug wires maybe, my spark plugs looked good too but really from the car sitting really took its toll.

 

There would be a lot I would check before I would assume the injectors are bad. First check fuel pressure and the resistance across each fuel injector. Does the car shake at idle, or only over a certain RPM? Also, what kind of exhaust work? If it was up by the engine they may have routed your wires poorly causing one to sit on your manifolds and burn through. Injectors may be your problem, but would not be my first suspect.
