Acceleration - "CLONK!" - idle running doesn't work!
 

Hi!

I have a 350z 2003 with a ProCharger supercharger and front mounted intercooler kit. Lots of other mods but I think this is the one most in question right now.

I had the car out for a drive yesterday and accelerated in first gear, full throttle. Just before I was gonna put it in second gear I heard a "clonk" sound (can't describe it any better) and after that the car started behaving differently. It lost power, the exhaust sound was different, it had to "struggle" more on low RPM's and the biggest issue was that if I took my foot off the gas pedal and didn't give it any gas at the engine stopped. It seemed like the idle did not work at all.

I have checked with a few people and one theory is that some kind of pressure hose somewhere has come loose. Maybe some pipe to/from the intercooler has come loose?

Anyone with experience from this issue? If this is the problem, is it hard to fix? Pieces that have to be replaced?

All help is greatly appreciated!
