So here's the deal... a 1991 KA24DE with 110,000 just rebuilt. Not doing so hott.

The 240 will idol but then rev to about 2200 rpm's then go back to idol continuously. Is that a throttle positioning sensor error? Or a vacuum leak somewhere? any help guys...

It is spelled Idle. It might help you get the right people to open the thread. I thought it was a gag at first.

anyway, I would def go over all the vacuum hoses. Unplug the maf and see if it changes at all.
