Default [1993 Bonneville Se] Rough idle

Idle is rough, sometimes 1500rpm and somtimes jumps from 1000rpm to 3000rpm and back to 1000.

A few times the car stalled while standing.

What should I check?
Maybe cleaning the throttle body?

Thanks alot,
Sahar.

Welcome, Isreal.

When was your last tuneup? Plugs, wires, O2, fuel filter, air filter? Cleaning the TB and MAF might help, or you may also have a vacuum leak.

MAF/TB cleaning is in Techinfo. Link at the top of each page.

I had the same prob, it was the MAF, just be careful cleaning it,
but it is a quick easy thing to try

I agree we need more information on the last tune up. (and to unbadnitize WillWren.)

I believe you are the first member from Israel. Welcome
