Sluggish IAC motor?
'86 2.8: Between shifts, the RPMs stay high for way too longs, and I get into the next gear with the engine turning too fast. Sitting still, I can rev it, and the tach stays up there for more than a few seconds before slowly creeping back down to idle. Sluggish IAC motor? Dirty MAF? I already cleaned out the IAC valve seat and pintle. What next?

Re: Sluggish IAC motor?
Kill? Won't stall at all, just keeps the RPMs up too high for too long. After it calms down, it idles just fine. I will try disconnecting the MAF when the weather cooperates. BTW, after it warms up, and I disconnect the IAC motor harness, it runs GREAT.
