I’ve been a mechanic for many years, but my own car’s got me stumped. 2003 Mitsubishi Galant 4 cylinder. 70k miles. The last 2 weeks, after starting, it would high idle for about 5-8 seconds, then rev back down. But today, it will crank, rev up to a very high idle, and then die, all within a seconde or 2. It’s as if it starts for a split second but won’t stay running. I’ve found if I put the pedal almost to the floor, it will stay running, although it’s at a very high idle. Scanned for codes: None found. I suspected idle air control air valve immediatly, so I replaced it and to no avail. I cannot find a vacuum leak to speak of or anything. Any possible suggestions?

Throttle position sensor? My 95 Galant was very picky on having a clean throttle body, I am not sure if this is related at all. Have you checked the fuel pressure?
