Had timing chain and gears replaced. It idles high and the idling also bounces up and down. What could be the issue?

Re: 04 CAVALIER ROUGH IDLE Sign In
did it do this before you replaced the timing chain?

Re: 04 CAVALIER ROUGH IDLE Sign In
it was running kind of rough that week the timing jumped. Would it the map sensor or a vacuum hose to the map sensor?

And no it didn't do that before the timing chain was replaced. But on my car the timing is set by a computer.

The ignition timing is controlled by the computer, not the valve timing.

I had the codes checked and it gave a MAP sensor code.
