Engine Performance problem
1993 Lexus LS 400 V8 Two Wheel Drive Automatic 135000 miles
My LS400 intermittently stalls when I slow down at a light or make a sharp turn when the car is first used in the morning, especially on very damp humid days down here in FL. It will also stall after being driven a while, when I try to start up again immediately after turning it off and on occasion when I am braking while parallel parking the car.
My mechanic has recently replaced the idle control valve but this did not make the problem go away.
