This may be caused by a vacuum leak or your throttle position sensor check your vacuum hoses to make sure you have no loose or broken hoses.

93 3003 MERCEDES 2.8 DIDNT PASS SMOG NO CHECK ENG LIGHT ON SMOG GUY SAID EGR STUCK IDILES A LITTLE ROUGH BUT RUNS GOOD AT HIGH SPEEDS WHAT DO I DO?


run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

Idiling high, temperature guage not working. no check engine light on. no problems shifting, fan coming off & on, blowing hot & cold air. can drive it, but it wont start up right away &


Check the cable to the temp sender unit is attached if so check the unit is working with a ohms meter. check the throttle cable is not binding ,the throttle leaver stop at the throttle body housing should be fully closed .

Air conditoner stopped working in 2001 chrysler voyager. knob is working good just nothing is blowing out. before it stopped working, it would only run on high,


Sounds like your heater blower resistor lived its last life. They usually fail one speed at a time, until you're left with none. Should be able to pick one up at your auto parts store, and they should be able to get you close as to it's location. Most likely under the dash on the Passenger side. Typically, two 7mm screws and two electric plugs.

2000 stype jaguar runs rough while idiling at stop light. Car sometimes just cut off. Have changed plugs and filter and car is still running rough. It appears that sometimes the gas is not flowing properly...


This fault could be anything from a split or perished vacumn pipe somewhere on the inlet manifold to a mass air flow sensor and i would advise that you ask a local mechanic to have a look for you to see if anything is visable from a quick look at the engine .

My 1998 Explorer on startup idiling to high, it occasionally revs up and down while idiling. Is there a trottle position sensor that controls the idiling rpm?


there is a tps located on the intake where the inlet tube for air intake connects, it would be on the left side of the throttle body. does the trk run rough on idle? up/down sputter sometimes stall? Is check engine light on? if no light,check all vacuum lines for cracks/splits loose fit. do this by spraying carb choke cleaner on connections motor rpms will change if leak is present. also spray around perimeter of intake housing where mates with lower intake if engine revs you have bad intake gasket.I Just replaced upper and lower intake on my 98 and shazaam, runs like it should. but do your checks first,unessasary fixes are costly and **** you off.

Engine vibrates when idiling in drive only does not vibrate in park or neutral or reverse has new motor supports (all) recent tuneup cant determine cause (the motor runs so smooth except while idiling then...


Check your throttle body gasket, if it's leaking unmetered air it will idle high, this coupled with a bad ignition coil, plugs not properly gapped or old/worn as well as old/worn spark plug wires will cause a misfire that may not trip the CEL light. Also check your idle air control valve to ensure it's working and clean on the inside of the throttle body.

Air conditoning gets warm at idle. 1998 buick


It seems the automatic idling lifter (sensor) once you switch on the a AC system has failed and thus at low idling the Ac compressor clutch gives in stopping the compressor to spin.
You have to check tht system out.
Hope this helps!
