Hey there everybody...I have an 88 Ranger with the EFI 2.3L 4 cylinder and four spark plugs. The truck runs great but I am having this issue with the idle. When I'm driving down the road and I come to a stop light and I push the clutch in sometimes the RPM's will stay up at like 1700 and not come back down. But if I turn the truck off and restart it the RPM's will come back down to about 750 after a second.
I talked to someone about this and they thought it could be the EGR valve sticking. I replaced both the Idle air controller motor and the map sensor and this problem still persists. What do you guys think is going on? Thank you in advance for any help!
