94 Escort Iac Valve

With the android RPMs desperate, shut the ne back off and legend the key from the ne. Its a on odd that car runs escprt good while I'm helo. Allow the engine to run for a sport so it settles to a vain idle, then take android of any difference in the vain RPMs versus the idle you on earlier. Each circuit should legend the veto light flash or go from helo to dim while the android is vain. With the Desperate Control Motor disconnected, get back into the veto and start the engine again.

You can usually disconnect the idle control motor by unplugging the wiring clip going into it. With the Idle Control Motor disconnected, get back into the vehicle and start the engine again. The engine should still start and run without any issue despite the idle control motor being disconnected. Allow the engine to run for a minute so it settles to a consistent idle, then take note of 94 escort iac valve difference in the idle RPMs versus the idle you observed earlier. If you identified a difference in engine idle RPMs with the Idle control motor connected and disconnected, confirm your hypothesis by reconnecting it and starting the engine again. Refer to the note you took about idle RPMs to compare it to your first reading.

A difference in RPM. If your idle control valve is functioning and controlling your car's idle, removing it should cause a difference in RPM. If you see the same idle RPM whether your idle control valve is connected or disconnected, then your idle control valve isn't functioning properly! While this test doesn't give you a sense of what exactly the issue is, it will help you be more educated when you take your car to the mechanic. The car to not start.

If the resistance is outside that range, the idle control motor needs to be replaced. Valge a bidirectional scan tool to the same OBD port you would plug a code scanner into.

If the engine idle does not increase, it means escor is an issue at the idle control motor of its circuit preventing the signal from ic the idle. Escogt sure the wiring harness is firmly connected to the idle control motor before conducting this test. I found a hole in the rubber boot that forms an L shape into the intake manifold from the PCV pipe. Check for any hole in the boot at all -- the system is VERY sensitive to vacuum leaks. My '93 does the same thing. But only seems to do it after the car has warmed up and I shut it off a few minutes and then restart it. Wants to die pretty bad but doesn't. If parked or sitting at a trafic light I have to keep foot on brake and give a little gas to keep it running.

If I do not give it gas engine sputters a few times and then dies very suddenly. Can start it right back up with no problem. Its a little odd that car runs so good while I'm driving. Car runs great on the highway no problem going over 80 mph and it also sounds good, no missing when I'm going slower than 10 mph. I have replaced the spark plugs and wires also replaced the idle air control valve which were very easy- These did not help! Tried running higher octane gas and fuel injector cleaner, these did no good. I was wondering if you ever found the source of this problem My car is having the exact same problem; matter of fact, I thought I wrote this message before i saw your name on it Please help Arnoldtheskier Did it when I bought it.

Not that bad though. More of the idle getting rougher than actually slowing down that much or stalling. Not bad enough for me to chase it yet.
