i've got an 87 ranger 2.0l manual tranny and when i shift gears, especially from 1st to 2nd, when i depress the clutch the rpm jump way high for a couple of seconds and then idles down. the truck has bad rings and blow by and this didnt start until the blow by did. someone told me it was the fast idle solenoid that was on the fritz. is this true? i cant afford a new truck so if anyone has as cheap fix that would be awesome

I am not very fimilar with that engine, but I wonder if the PCV valve is shot? Has a compression test been done to verify that the rings are actually the issue? Can you replicate the problem setting still? Remove the PCV, plug the vacuum hose and see if the problem persists... Could be causing an intermittent vacuum leak, which would cause the idle to increase.
