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
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
Keep us updated.
