Helllllppppp!!! TECHS help me

Alright, put studs in a few weeks ago, just started driving it last week (2 days less than 5 mi each day), noticed that I had a intake manifold gasket that had split and caused a pretty nice space between intake man and head. Well replaced the gasket and got everything all sealed up nice. Well in the process of putting the map hose back on I slipped off the front bumper and broke nip off of map sensor. of course I took for a test drive adn she drove like $h!T. Replaced MAP sensor just about 10 mins ago, could barely get truck to crank, could be cause of coldness but i doubt it.

She builds a lot of boost now in the low speeds like 25# and is very sluggish to take off, almost as if there is no boost but i'm reading boost on my monitor. Engine still seems a little off almost as if there is a wierd stutter in the exhaust. the engine itself sounds fine, no pops, misses or anything just the exhaust. SHould I undo the batts and let the computer relearn the turbo press and adjust for the new sensor???

Alright nvm, i think i found the major issue, apparently had a FICM connection loose from pulling and moving the injector harnesses to get the intake manifold off causing low ckt codes on cyl 3 & 8. I snugged those up did a vgt relearn and voila!!!

If i knew how to delete this post to keep from showing that I learn from mistakes I would.

All good man, learning is what keeps us moving forward. Life would be pretty boring if we never learned new stuff!

Your not the first with this, and you won't be the last. The problem is, someone could have said to check the harness, and you might have said you did twice, but sometimes the 3rd time is lucky.

I did offer this advice to him yesterday morning...

From this other thread he started... Turbo Leak
