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?

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.
