I recently replaced the intake manifold gasket on my 91 Ford Explorer Sport. I had to remove all of the vaccuum hoses and many of the sensor connectors during this process. Now that it is back together, it does the following:
- Engine revs up to about 1500-2000 rpm immediately after start.
- After about 30 sec to a minute it settles down to about 800rpm, but idles rough.
Everything was fine before the repair work.
Could this be a missed vaccuum line? Or a missing connector? I'm pretty sure I conencted everything the way it was, and I donyt hear a vaccuum leak.
Power seems normal during regular driving.
Any thoughts?
Thanks, Dan
