Unstable idling


Do the throttle body cleaning and re- learn the idle speed control. Let it idle for 10 min.

2003 Toyota Camry 166000 mi., 2.4 liter 4 cylinder. ONLY WHEN CAR IS HOT, idle drops off, engine stalls, must step on accelerator to keep from stalling. Otherwise, idles normally. New spark plugs,...


Some "check engine" light in your dashboard? If YES, need to scanned the PCM (computer) to know exactly what fault code is stored there. If NO, the crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

Also, keep in mind that on the 2.7L V6 and 2.4L 4 cylinder, a defective Exhaust Gas Recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Stalling synthoms... you can have a plugged exhaust, plugged fuel filter, bad airflow meter, problem with the ignition system, incorrect timing belt/chain setting, and failing fuel pump....I'm sure there's more but that should get you thinking.

Keep us updated.

Does a 1991 toyota cressida have a timing belt or a timing chain? If it is a timing belt, how often does it need to be changed? If it is a timing chain does it need to be replaced at all?


On 1997 & prior models, the timing BELT interval for vehicles operated under conditions of excessive idling & or low speed driving for long distances, replace at 60,000 mile intervals.

02 rendezvous 3.4L missing randomly on all


You need a live data scanner to look at this when the problem occurs in real time, I could guess but that would waste your money and my time.

do a compression test to make sure the cylinders are in balance.
if the compression is good,change the plugs wires cap and rotor.
