Thanks for responding, No I did not check the pressure I have never done anything like that before. I figured it could be the fuel pump But since I am a amature back yard mechanic. It was running fine till I got on it.I think the code reader said that several of the cylinders had misfired . Then the code came back as number one cylinder was misfiring. When it showed many cylinders misfiring the check engine light was flashing. I read that thats not good for the Cats. My emission comes due in Feb so I got to fix it soon. There are few who wish to work on my Crossfire in my area. That is why I try to fix it myself.Wish I knew someone local to me who could help me figure this out.
