    Z20LET Problems

    Hi guys i need ur help, I was driving to work this morning and my coupe turbo decided to lose power and the TC light came on and the EMl. It was
    Missfireing and stalling. I unplugged the afm and it ran fine so i though i'd better go and get a new one. I fitted the new one and cleared the p0100 code and it was the same i.e the TC light and EML came on and stalled with the missfire. So i though maybe its a faulty afm so went back down to vauxhall's and got another done the same again. Any ideas on what the fault maybe??
    I have tried three afm's now and cleared the codes each time. I have done the earth mod,changed spark plugs,new coil pack and its still the same.
    Any Info/help would be great.

    agree with danny, check all your boost pipes for splits and security.
