Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
2000 Mitsubishi Galant 2.4L 4cylinders: Hello I need help with my 2000 Galant. I bought it with a blown head gasket and I've replaced the block with a good one and had the Engine Head fully rebuilt with reseating the valves, new valve stem seals etc. Once everything was back in, all fluids topped off. It fired up fine. However when it reaches operating temperature it hiccups, rpms drop, and then stalls.
I have to adjust the Idle Screw to Idle at 1600 rpms for the engine to stay on. At 1600 rpms, shifting into D or R would let the Galant drive but braking would result in stalling.
While idling between 1000-1600 RPMS, there is a pattern of timed misfire. Misfire... 6 seconds... misfire... 10 seconds... misfire... 6 seconds... misfire... 10 seconds... misfire

Hello Doug, thanks for your reply.
The compression is the same, hot or cold. There are no additional codes other than P0300. I drive it like a stick shift and put it in neutral everytime before a complete stop and have driven it 80+ miles with no additional Faults nor Pending Faults. I will try and get the fuel trim readings tonight. Please provide me instructions on how to monitor fuel trims or what measurments I should be looking for. I have OBDII laptop software that can provide live PID data as the vehicle is on. Thank you Sir.

The reluctor is to the right. I had a shop I know double check it the timing for me as well. The oil pump at the lower right has its arrow lined up with its relevant timing mark.
Let me correct myself, the "V" notch(on the blade) is to the right of the the stationary mark behind the blade(reluctor?). Yeah I noticed when the timing belt is on, it takes two full CAMshaft turns for the oilpump to line up to TDC with the CAMshaft and Crankshaft.
Yeah I noticed I had to turn the Crank and Cam a number of times for the the oil pump to realign. I will try and get those fuel trim measurements for you later tonight when I get to the Vehicle. Thank you Doug.
