    2.2 Ecotec random missfire mystery have log files

    2004 cavalier with a light hptune. I have two log files if anyone is willing to look them over and maybe see something im not that is off? I have done compression test, icm, timing set etc. Only codes are random missfire, idles horrible and super rich. Has no power at all. If someone can please take a look at my log files for me I would greatly appreciate it.

    Post your stock file and your modified file

    It makes it easier to troubleshoot.

    we dont need a stock file. the repository is full of similar files if not the direct stock platform file. just post your tune file of which you want reviewed or are experiencing issues with.

    no it does not. any file ending with .hpl is a scanner log file.
    the file requested is a .hpt file which is an editor file.

    I dont know what version of HPT you have but here is how you can post your tune. Go to VCM editor click on file in the upper left corner>recent files>a list of files will show up and pick the one you are using and download it to the tune repository. I am interested because you have the same ECM as me. You mention that the car has a Hahn kit on it do you know if Hahn did the initial tune? I tuned mine myself and I would really like to see a Hahn tune. A list of all the mods on you car is helpful for everyone here.
