I just changed head gasket-timing belt-water pump. Now when I start the car, it goes from 1000 rpms to 3000 rpms constantly. Changed a couple of sensors but not sure if being a tooth off

Question type: Maintenance & Repair

So it keeps reving from 2000 rpms to 3500 rpm constantly. Could being a tooth off on
timing belt cause this?

Possibly a vacuum leak. Recheck all vacuum lines to see if they were installed correctly.

We looked for all that even redid intake manifold gasket. Any ideas what else it could be?

Lik water out the head
