Why does a '93 Ford Tempo GL suddenly have a high idle?
Binding throtle linkage or idle control solonoid not working.
With mine it was the IAVC(idle air valve control) on my 94 2.3L Tempo. I got the part used for $10 at junkyard($54 new at Knetch's). On some, the springs stick so you can try spraying it with carb cleaner to loosen them up. Although on mine, the springs moved but you could blow on one end and air came out the other side. On the "new" IAVC part, air wouldn't pass through but fixed the high idle perfectly! Before you take it out, try tapping it with a hammer to see if it temporarily changes the idle any. If so, that is certain to be your culprit for sure! It was mine!
What would cause a 93 Ford Tempo to suddenly start idling very fast then after replacing the mass airflow sensor and throttle position sensor the problem remains the same?
Stuck throttle plate vacuum leak bad TPS I used to drive mine over 500 miles from DC to Columbia SC and it would idle high once I finally stopped. A guy did something to the throttle to loosen it but....the solution is the idle air control valve. Its right in front of the windshield wiper fluid. Its as easy as replacing the TPS which is two bolts holding it on but make sure you get…
you have to turn the idle screw down ?? ? ? ? ? ? ? ? ? ? there are 2 of them. one on the right and one on the left. the left one is general idle and the one on the right is for air-conditioning idle and high power output idle ( rev higher ) A vacuum line may have come off if it has started revving.
You don't. The ECU controls the ISC (Idle Speed Control Motor) which adjusts the idle. If idle is out of control (too low or too high) try gently tapping the ISC with a small (0.5 pound) hammer or a large wrench while the engine is running. If tapping the ISC makes a change in idle speed, you need a new ISC. Clean the throttle body whenever replacing the ISC. If the ISC is not the…
1998 Ford Ranger 25L 4-cylinder fast idle even after new idle air control valve replacement what now?
fuel pump Not fuel pump. Idle air control motor. Replace or remove and clean. Simple and quick job. Its normal for this particular motor to lope at idle because Ford used a high rise exhaust valve which in return required the cam lobes to extend creating a longer revolution than the intake valve. Thus, the "lope" you hear or feel is basically power. FORD POWER!!!!!!!!!!!!! answer On fuel injection systems, the usual cause for the…
