Hope you guys can help me... I have been having a problem with my truck as of late, check engine was going off like crazy last week. Turns out pcm/ecm connections were loose. Thats been fixed, but now if i lay into it, it throws an overboost code and sets the check engine light. Juice has been disconnected from engine, but monitor remains. When i go to clear the code, the brake light comes on and i can hear something clicking underhood, then the code goes away. This shouldnt and hasnt happenned before.

any help?

thanks.

Take the edge completely off. Even with the injector plugs off, the map sensor can still change things when hooked up.

What year? Fill your sig out so we know.

 

I don't think the attitude will work correctly with the Juice disconnected.

 

If he's just unplugged the injector plugs and left everything else, it would still read ECM parameters and EGT's. (possibly)
