I have a 2000 Galant 4 cylinder, when I start it, it turns on for about 30 seconds up to 2 or 3 minutes but then shuts off. If I hold the gas pedal down and turn the key it stays on as long as I keep it acelerated, when I let go of the gas it shuts off. Also when this problem started the check engine light turned on. When I put the computer on it it marks the cam sensor, but when I did the test it came out good, I also erased the check engine light and the car ran fine for 1 day and started the same problem again.

Check your harness wires on the cam sensor...they may be frayed or loose...My brother had this same problem and it was the wires.

having same proble did you fix it and what was it? pozopozo71@yahoo.com
