Is It Possible?

For a year, my car has had a wildly surging idle and stall problem. It occurs when the engine is cold or hot. Whenever it wants. It started off occaisional then got progressively worse.

I have done everything on the idle/surge sticky here.

I cleaned the throttle body while it was still on the car by spraying carb cleaner and using a tooth brush.

When I started the car, the idle did seem a bit more constant. I let it run for several minutes and it did not surge or stall. I drove it around for about fifteen minutes and it seemed to run fine. No surging/bucking or stalling.

Is it possible that a dirty thottle body can cause wildly surging idle and stalling?

Thanks for any input.

I would think that it certainly is a possibility that if the TB is sticking it could cause stalling. I guess the most important thing is that for now it appears to be fixed, right?

"For Now", but I have had that in the past too. When I get 10 hrs. of drive time with no surging/buking or stalling I will consider it fixed.

Thanks for the input.
