Question about Ford Contour

Revs go up down idle

1999 contour 2.5 V6 engine revs up and down even when in drive. Replaced the AIC motor and it seemed to work proper but then started to howl and now is acting the same but with a howl now.

SOURCE: Rev counter jumps whilst idling and then engine cuts out

Your problem sounds as if the thermo sensor....which controls the air fuel ratio when engine is cold....is faulty. It is a common fault on this model.
This is not an expensive part, and takes only a short time to fit.
Good luck

First thing in morning start engine but over revs at idle speed. once driving engine warms up then seems ok. finish work at night same thing happens again. does it mean its sucking air in somewhere or...


Hello Mark,
You should be looking at the idle air intake control motor, as that will often become clogged up with sludge or grease /dirt combination that will prevent it from working properly. When it doesn't work right the car will either stall a lot or will rev very high when cold (because the computer will try to make up the difference and prevent the engine from stalling. You can clean it using carburetor cleaner sprayed on it's shaft. If it still won't work correctly the motor should be replaced.
Please use the following link to view to all the possible placements of this motor and how best to clean it;

Have the engine hooked up to a diagnostic meter to see exactly where the problem is. No sense in replacing a lot of parts when only one or two may be necessary.

You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

Revs up and runs rough then stalls, it runs very rough, it can barely idle, put in gear and it stalls


I would like more info on the vehicle, as to the engine size. There are vacuum leaks on this engine, both the 4cyl and 6cyl. The injector lower seals are prone to cause this condition, but to check for this and to do it safely, is have it smoke tested with the proper test equipment. The EGR valves can also stick partially open, causing a rough idle and then a idle fluctuation and a stalling problem. Another poss cause is the idle control motor is failing. This vehicle should be taken in for service at a very reputable repair shop. If not properly diag, will cost hundreds of dollars just to "PUT PARTS ON IT UNTIL IT RUNS GOOD".
