maf is plugged in, so is stock boost solenoid, my problem is i checked everything probably about 10 times and cannot see anything that could possibly be causing this, it is exactly like the throttle is stuck wfo, i'm going to tear it down tomorrow morning and go from there, the shame is the car was running great before i did this, figured an mbc would be an easy mod..... wow, was i wrong.....

It IS an easy mod

You managed to disturbed something and frankly guessing at the problem without having watched you install it is almost impossible. All we can do now is come up with likely scenarios as to why the idle bumps up, its obvious now that the MBC isn't at fault.

Tell me does this mbc kit happen to come with a in cabin adjusting point?

You see this picture here?


I want you to check the spring above the drill

i didn't do the remote interior control, everything is under the hood, i checked the throttle cable, mount, and return spring, all are working as they should, i'm starting to believe something happened to the maf (it's the only likely thing that could cause my problem even though i have always taken great care when i remove and replace it)

Check your throttle cable - Make sure your throttle body spring returns to completely shut. Sounds like your throttle body is stuck open. This is not directly related the the boost controller but something was bothered during installation.

As far as ECU training goes I always thought that you turned on all accessories, while you were training your ECU, lights, AC on high etc. Can someone confirm this?

it is exactly to the diagram, i know (from everyone here telling me) that the mbc is not causing this problem, but it ran perfect until i installed it, i have been over this thing countless times and cannot find one thing wrong..... could something have happened to the maf that could be causing this..??????

Double check the vaccum connection on your DV and wastegate. There is a small chance that the system isn't depressurizing as it should.

ok, if anyone is up in pa, you can come give me a good kick in the ***, when i removed the top i.c. piping, i used paper towels to block off openings to keep any dirt from entering, one must have fell too far into the top flex pipe for me to see ..... and yes, it was holding the throttle body open.... THANKS TO EVERYONE FOR ALL THE HELP THOUGH.... go ahead, let the bashing begin.......

the towel was paper, it wedged itself right befor the flapper in the throttle body, it was not inhibiting the movement of the throttle at all, but definetley blocking off almost all airflow......... for thegame, i'm in butler
