I have a 2000 ES 300. the check engine light is always on--I was told it was not vital--but when I stop and leave the car in drive right now, it starts to flash--stops as soon as I accelerate.
I drive 50 miles a day one way--car just had major work done (timing belt, knocksensors, fuel and water pump, sending unit, throttle position sensor and gasket, mass air flow sensor, uppper and lower intake gasket, inside and outside accessory belts.
It was running fine until yesterday--started the rough idle when stopped in gear. Last night and today the "stutter" started--when maintaining speed, RPMs went up to 4000 when driving at about 68 mph.
Not regular stutters, kind of like a sudden deceleration but speed doesn't change.
