    when i installed my sd headers i coverd my a** and removed my plugs so that i didnt break them.
    im will billboost37, a huge vac leak will cause it. but it sounds to me like u may have cracked a few plugs also. you did extend the rear o2 sensor correct????

    Plug your maf back in and please do your wallet a favor, stop trying to diagnose stuff that you didn't touch. This is something you touched/broke. You know you have a vacuum leak, it acts like a vacuum leak, it smells like a vacuum leak.... I'm gonna say...most likely ..it's a vacuum leak. Unplugging the maf put you on the table which runs rich etc. That's way it seemed a little better for a bit.



    Chris..next time you want to free rev past 4K punch yourself in the nuts. The only good that'll come from that is learning how to swap a motor. I'm thinking you don't want to do that.

    Thanks to everyone, I got it fixed today. Went and picked up the evap solenoid and some new plugs just in case. put the solenoid on, still ran crappy. So on to the plugs, where under further inspection there was a hairline crack on 2 plugs (looks like you and I are the same starscream haha).

    I really need to be thanking you bill, you sure know your stuff. I might just have to buy you a beverage or two if you ever make it down to NC haha. I usually don't throw my wallet at the problem. But with a newborn and working long hours. It didn't leave much time to troubleshoot. I'm not at all new to the 3800, ive had a 99 since i was 16, and now my 2005. Been in mechanics for a while too. Im a helicopter mechanic in the Marines, so you know I deffinately mess some stuff up LOL. But once again thanks everyone and sorry for sounding n00bish.

    Chris...we've all done it.. That's why I was a little harsh.. you needed to refocus.

    Am I the only guy that always pulls plugs to put headers in? We don't have a lot of room....why not give yourself as much as possible?
