    bad iddle and rough running after mods

    hi i just installed a turbo xs front mount and a megan header w/ up pipe and megan turbo back exhuast w/ high flow cat and i installed a cobb stage two access port and now my car would not stay running it would start then die. after 4 or 5 times of tring that it strated but was spuddering and missing basicly could not idle at any smooth rpm at all. The car keeps missing and spuddering i realy do not have any idea what is wrong could venting to to atmospher have anything to do with it? or does it sound like a vacum leak or maf sensor problem? has any1 had these problem as well

    try reflashing back to stock. See how that affects it. Also, get a OBDII Code reader (but your check engine light should go off if there is a problem with leaks or MAF.) The reader can tell you what is wrong if there is a CEL. Did you check the lines to the front mount to make sure nothings loose or leaking?

    Is your intake stock? Also, if the headers are leaking, that might lead to a rough idle. Check for leaks around the headers. That hits me as the most important part of what you changed. If your car is dying after a start, your inter cooler might be the problem. I would just go back over all of the lines, make sure there are no leaks.
