While driving the other day , My 89 sse suddenly started jumping, feeling like the transmission was going , when i stopped at a light the car stalled and was not idling steady at all around 300-400 rpm ..i thought it was a vacuum hose that disconnected, but it wasnt that. the check engine light comes on now and then while i drive at 1 min intervals..I was told this was the oxygen sensor..Has anyone had the same problem with there car??

Read this & see if this is your problem?

I know you don't have a new IAC yet, but has yours been fiddled with lately? Cleaned? Adjusted? If so then you may have to re-adjust it back to normal. Also, if you haven't cleaned your TB lately, it may be gummed up with carbon & the pintle on the IAC is stuck. An O2 sensor will only cause you to either burn less/more gasoline when it burns out.

When you find the problem and if it is mechanical i have an extra complete throttle body for sale cheaper than any part store.

Ok, I changed the o2 sensor, no difference, Where is the AIC located on the throttle body, I do have another bonneville for parts, I would like to take the peice off I need, thanks for your help guys

OOPS...I cleaned my TB last week..I didn't remove my MAF...so far so good...
Next time I guess I'll remove it..Thanks

I wasn't so lucky when I cleaned mine. Luckily I got me a used MAF for 50 bucks, but definately remove before cleaning.

So...did yours just go out instantly...I mean YOU knew right after cleaning right...??

yep, car wouldn't start and i pulled the codes and up it came.

COOL...(for me)...Mine is running FINE...thanks

Hey guys...I will be taking off the whole throttle body tommorow for redoing...the maf sensor..that is the square box that is attached with three screws..facing up right? I also have pics posted now on yahoo..
