My car (95 VR4) can start up immediately in the morning (when cold). The issue I'm having is after I drove it for about 30 minutes or so...as long as it is fully warm up, then I turn off the car for about 20+ minutes, I will have a hard time starting it back up. If I turn off the car and start it back up right away, it will start no problem, its just happens after sitting for a period of time..around 20 minutes to 1 hour.
The symptom I got is it will not maintain idle, I turn the ignition, it starts to idle 1200+RPM initially, and it will slowly drop to 100RPM or 200RPM and off. This process is about 5+ seconds. I started it again...while pressing the gas pedal, no throttle response at all, its like the gas pedal not having any effect at all while the RPM from around 1200 drops to 0. It struggles maintain a idle. I kept on starting the car for maybe 5 to 7 times and pressing/pumping the gas pedal, finally the gas pedal responds and I can maintain the RPM at 2000RPM while pressing the gas pedal for about 10+ seconds, then it goes back to normal idle. I do smell some gas from exhaust after all of this. This happened to me on 4 different occasions.
Any suggestion to what is the problem and how to fix it? Thanks in advance.
