hey all, been having a boost issue! car idles great, pulls great in first and second occasionally in third and never holds boost in the later gears? its hitting soft limp i think, umplugged the maf no change, unplugged the n75 no change, guess the ecu is cutting fuel aswell!!
scanned her after deleting the codes and going for a drive, got the one in the title and the weak maf signal one... so ive ordered the maf sensor and now im puzzled as i replaced the n75 today?
if it were a leak would it be in every gear???
also i suspected the valve between the rocker cover and turbo intake pipe so i removed it and it was full of gunk, figured i'd blank the tip side and go for a spin, it wasnt perfect but ran alot better and held boost in third and fourth pretty well!? i soaked it in wd40 and refitted but havent had time for a drive yet?
lastly the new n75 is black and the old one is brown, the brown one was fitted with the wireing connector facing the engine and the longer horizontal spout entering the tip, to have the new n75 facing the same way the shorter spout enters the turbo pipe...? is it the wright way round?-)
ive had this car a week by the way and knew it had a few issues, i like a challenge but this engine is so complicated...
really just trying to give as much info as possible encase anyone else has had this problem?
