1995 Mitsubishi Diamante Q&A

1995 Mitsubishi Diamante Question: Car cranks and runs until you put in gear, when you hit gas rpm drop and car die

I've changed fuel pump, fuel filter, fuel relay, the main computer, did a basic tune-up and the car still won't drive. If you take your foot off gas pedal the rpm's will bounce back up. Any other suggestions? -
Answer 1
Any trouble codes? Check engine light on? Fuel pressure reading? We need scan test results as to prevent guessing! Have throttle position and mass airflow sensors tested especially. Scanner can do that. -
