My car is acting very strang, the tachometer periodically works, most of the time it doesnt. My car has alot of trouble starting and usually doesnt. And when it does start, it will stall after a few minutes, but usually it will misfire a few times and then turn off. The SES light is on and its throwing codes P1641 and P1642. I brought it to my mechanic and he checked all the relays and grounds, and replaced the ignition module and crank position sensor and nothing changed. I am running out of options and my mechanic thinks I need the get my PCM reflashed. Anyone heard anything like this before?
