Hey everyone,

ever since i bought my SSE/SC i've had a very rough idle. recently i changed:

plugs (AC-Delco)
plug wires(AC-Delco)
fuel filter
air filter
cleaned the TB
Cleaned the PCV

this improved the idle much, but at idle in drive, i still feel a bit of a surge and uneven idle through the steering wheel. any one have any idea'*?

Thanks,
Devon

Possibly a weak coil. Could also be a weak or failing FPR or fuel pump.

i checked fuel pressure, it was strong. only thing i havent checked it coils

How well did you clean the IAC passage in the TB, and the IAC itself?

It'* either fuel (could still be injector), spark (probably coil at this point) or air.

Does it seem like this????

Vacuum leak?

checked all the vacuum lines yesterday, all seemed good, not dryrotted either

lakevillessei- thats much worse than mine is. i cant even hear it the bad idle, i feel it through the steering wheel.... it sounds fine

Lucky you.


I would start looking at the vaccum system.

Could the EGR valve be another possibility?

My 94 just started doing this today. At lunch it took a few seconds for the car to get started (cold). Then it was idling really lousy and nearly stalled. I revved in N a bit to get er back going.

Just now my SES light went on. Idle is better in drive, but really noticeable in park.

taking it in tomorrow.
