I have a 2005 Crossfire (.not SRT) that is driving me nuts. I have replaced mass airflow sensor, camshaft and crankshaft sensors, new fuel pump and new RCM. Changed the spark plugs and it simply will not stop misfiring. I did notice that when I moved the car today, the brakes had no assist. I had to literally stand on the pedal to get the car to stop. Related? For more back story, initially it just turned off and would not crank back. Replaced the likely suspects and still nothing. Just turning over but no fire. Wondered if it was getting fire, so I sprayed starter fluid in the intake, and thought I had ignited a bomb. After I went inside and changed underwear, I tried it again and it rain for a bit so I assumed it was getting fire. That's when I changed the fuel pump. Had bad relay on RCM so I replace the module and now I get 0300, 0302, 0303, 0304, and 0306 codes when it runs. Also the check engine lights comes on and then starts flashing. I am literally out of ideas. Live in a small town with no easy access to specialists. Any recommendations (not involving matches) would be most appreciated.
