Car Dies Once Plug Afm In

[timr32gts]

hey guys, this is what happened, i was driving and after a boost the car made a loud bang after i changed gears, then the car wouldn't hit boost anymore as soon as it revs up it hits a limiter at 3k revs then dies.

I checked all the intercooler piping that seems all good, i thought it was the AFM because when i unplugged it then the car idled fine and doesnt stall, then when i plugged it back in the car starts then drops revs slow then stalls,

so i bought a new AFM put it in and it started going all good then after 2 minutes done the same thing and stalled,

Car is an r34 gtt.

Recheck all cooler pipes. Every single one. Loosen and check theyre on correctly then re tighten.

Also check the intake to the turbo

ok ill go over intercooler pipes again, i did check the front wheel on the turbo its fine spins freely hardly any shaft play.

Definitely sounds like intercooler plumbing. Have done the exact same thing a few times. Make sure every single clamp is tight as Jez said, don't just look at them and assume they are tight. If they are all good then my money is still on a vacuum leak, but seeing as it happened after boosting then I am quite sure you will find it is the clamps.

thanks for the advice ive found it now the manifold was cooled down, the elbow silicone hose off the turbo to intercooler is rubbing on the manifold and the heat must of put a hole in it then it must of burst and put a 8 cm rip in the back off it.
