New Timing Belt - Cause of stalling?

[DagnyT]

I recently had a new timing belt put on and since then I've had stalling issues. The last time I had stalling issues at a low idle it was carbon build up in the air idle control valve. I cleaned that again and it didn't seem to help at all.

Someone said that maybe in doing the timing belt job that something isn't lined up properly causing it to stall coming to a stop or as it goes from idling high to suddenly low and it just quits.

Any thoughts?

The belt just pulls the cams around to activate the valves correctly. Your stalling problem is likely not that.

I was told if everything didn't line up correctly with the new belt install that could be the cause.

I do know that I didn't have this problem before the new belt went in.

Easiest way to tell if the belt is off is at idle. If it's rough and it wasn't before the belt change, the timing is off.

That does seem to be the case. I just took it back to the shop that did the install.

I hope they figure it out without hitting my wallet!

If the belt was not lined up correctly your wallet should not be affected at all, but the paycheck of the tech who did the job should be.

A tooth of will cause ruff idle rough and could course your issue. Pros and DIYers Het this wrong ever so often.

If the problem started right after the timing belt I would assume (yes I know) that it is associated some how. May not be the belt itself but something that broke or fell off. A lot of things taken apart. My wild guess is a vacuum hose or something associated was not put on right and you ahve a vacuum leak somewhere.

If they are good and honest they will find it.

Let us know what they find.

I will definitely report back. They asked me to bring it in Monday. I know the guy personally that worked on it and he thinks maybe a tooth is off but needed more time to look at it. I will suggest a possible vacuum leak.

Thanks.

most vac leaks raise the idle speed. The belt off a tooth is the most likely.
