Ok guys.. I am hope ing that some may have experienced this..

My stock t25 blew out.. So I swapped in the T28. I put everything back together and fired it up.. Now I have a ruff Idle and the car spits and boggs.. I figured ok I will put in new plugs so I did and I fired it back up and still has the terrible spit sputter bogg.. So I figured I would see if maby I unhook the O2 and see what it dose and still the same thing.. So I then unplugged the Maf and it idles down and fine for about a min and then shuts off. I tried to swap in another maf and get the same thing.

When I primed the turbo I unpled the CAS and turned it over for a few seconds then plugged it back up.. Could I have done anthing by doing that?The car starts right up bun runs like crap.. Any advice? DO you think I have a bad maf ( I tried 2 and get the same thing) AHHHH... I need help...

Have you checked all your intercooler couplers? Make sure they are tight! Also make sure you have all your gaskets on and everything is tight! Also one last thing check your vaccum lines! That's where I would start to check.

Yea I'd put my money on a leak, either intercooler, or vacuum. Most likely IC, I had this issue, and I made a boost leak tester and found I had 2 different leaks. Both were on the hot side btw. I suggest making a 6$ boost leak tester, it'll help you find any leaks FAST, and with ease.

I will do the boost leak tester.. I checked the vacume lines and then I cleaned the IAC and checked the IC pipes.. I am stuck I am also gonna trow another O2 in and change the plugs out again.. I may have fouled one..

Don't worry about the O2 sensor, it wont affect your idle. In fact, just for the mean time, run the car without one, you'll just run a bit rich.
