My 2001 Lexus GS300, when starting the car up it will start and then start to die after 2sec. What does that mean? When I tried to start up the car it will start and run for about 1 or 2 sec and then it automatic turn the engine off. Once the engine is shut off, I could hear a loud humming bee noise coming from the Throttle control motor/ idle control valve. I have tried all kind of method. Like start up and press on the gas, that didn't helps either.
The car have near 75,000 miles, well maintenance up to schedule. I'm not so sure what is the reason that caused this. My best guess would be the throttle control motor is the issue. Due to the noise coming from this motor. So I end up purchasing a new motor from the dealer. But the question is there are some kinna keyway or special precaution I need to watch out before installing the new throttle control motor?
My friend is a mechanic too and he just told me there is a certain clocking or setting I need to do before installing the motor. Or else the car will Idle up and down. And that is the reason, I tried to avoid is the idle issue. The motor gear on the throttle control motor seem to move freely when you move it with your finger. And on the Motor I do not find anything that have a mark or keyway. Do I just installed and tight down the bolts? Also, what is the torque valve for this bolts?
have the same problem?
