ok so i did a leak check and i have none (i used the tennis ball method), i read on another forum that it could be the n75 valve, so i went ahead and checked that, i read to check it to disconnect the top hose and to drive it and see if it boosted up, it did so does this mean i have a bad n75?

 

So i cleaned the maf sensor with the cleaner from auto zone, scanned it i got the lame code as last time p0102 we erased it and this time it seems like its gunna stay off
But i think im still in limp as im only boosting 4 psi occassionally it will touch 5 psi if im lucky. Does any one got any ideas?

 

Start by checking for leaks in the boost gauge lines just to eliminate a tail-chasing situation. If it checks out ok, check all the lines to your N75. YTou should have a DTC stored if it's in limp.

 

ive checked the boost line multiple times so im 98% sure its not that, my cel came back on
but what is a DTC?

 

i also checked the n75 today and put new hose clamps on it and checked lines
whats the filter above the n75?

 

DTC means diagnostic trouble code. What code is stored?

 

oh sorry
thanks for the help
the code that i keep getting is P0102

 

Not to keep beating the dead horse BUT

P0102 is a MAF sensor code. Problems with the MAF sensor will cause the lack of power you are describing. Its either the MAF sensor or a wiring/connection problem to the MAF sensor.

 

So its the same code again. I think you're going to need a MAF at this point if cleaning the MAF, TB and TB adapt hasn't worked. You've eliminated boost leaks and vacuum leaks, so the code points to MAF or wiring.

 

Alright well i guess tommorow ill check the wiring then if thats not it ill bite the bullet and get a new maf sensor and hope that fixes the problem. Thanks for the help
