Question about 1990 Ford Escort

1 Answer

Very high idling

Vehicle has a mind of its own. It idles sometimes 4000 rpms, then drops. At times it seems like i have cruise control on while driving. Have lubricated all of the linkage that i can find. Not sure on what to check. Could it be the TPS or Idle ControlValve. Please help.

Hi, try disconnecting the linkage from the butterfly shaft on the carb. You should be able to turn this shaft thru a quarter turn by hand, and self return by means of the spring. If this is not free it may well be your problem. Is it a twin throat carb? then check that the secondary butterfly is closing fully in the throttle "off" position.

Idles at 1000 - 1200 rpms won't drop


high idle could be caused by air inlet duct collapsed loose or air filter element clogged,idle air control valve failed,idle air inlet passage or throttle bore is dirty full of deposit,mass air flow is dirty out of calibration,throttle plate throttle shaft or linkage is damaged or leaking.have vechicle code scan first before buying new parts.

99 mercury sable automatic trans vehicle idles very low randomly even stalls out sometimes high idle occurs as well reaches about 4000 rpm at times. engine light threw 4 codes, all to do with o2 sensors...


Sounds like a broken or torn vacum hose, pcv valve clogged, or bad Idle air control motor. Did you spray carb cleaner on vacum hoses or near the plastic intake., and did the motor rev up or down? Those codes represent a lean condition which means most like a vacum leak or clogged idle air motor. Sometimes the intake manifolds crack or the intake manifold gaskets crack. FInd that vacum leak or inpect iac motor
