2000 Mitsubishi Magna Repair Question
When i start my car it revs between 1500/ then just stops
See if there are any codes stored by the computer. You should be able to find places that will do it for free. Check the throttle position sensor & Idle Air Control. It could be a problem with the cold start circuit, supplying too much fuel when starting cold. Rent/borrow a fuel pressure gauge from a parts store and see what sort of pressure is present at the regulator/test port.
