Thanks for your reply wazzer. The temp sensor was a Haas from euro car parts. Basically the temp guage sits at 90 in town but always drops to 70 75 on motorway speeds. So im guessing thermostat is turning on too quick and cooling the car down prematurely.
So recently i cleaned the throttle body out was prettty gunked out but not to a extent where i thought it was out of the ordinary considering the car was running rich according to previous fualt codes. And i just fitted a forge 008p dv. Car feels normal under 2k revs now this could be due to the throttle body clean. But in boost again its very erratic lots of flat spots between 2.5 to 3.5k then it picks up again does feel better at least im not having the sudden powerloss as if ive hit the brake. I personally cant think of anything else just picked up a bargain mk4 r32 alloys with almost new tyres for £200 as well car looks great but this situation is killing me now cant enjoy the car
.
Basically so far:
Ive changed the maf bosch oem
Changed the temp sensor Haas brand
Changed the dv forge 008p
Changed the n75 valve to a prefix E not the J everyone seems ti slag off
Cleaned the throttle body
Checked most of the hoses i could without going to deep seem fine no visible or audible leaks.
Got a turbo cleaner now gona run that through it today any one done this before where do i exactly spray this?
Also any other suggestions?
