I am having a problem with my R32 and I have tried everything.

It drives fine for the first 5-10 minutes, then it goes crap....lacks power and won't accelerate. I am getting no error codes. Here are the things I have replaced.

TPS

AFM

KNOCK SENSORS

FUEL REG (MALPASSI) - SWAPPED FOR MATES ONE

ECU

IGNITION AMPLIFIER

It has a Bosch 945 (550 hp) fuel pump which is less than a year old

a Hybrid Hyflow t3/4 spec turbo

Malpassi reg

I also just rebuilt the engine. Forgies and stuff.

I have tested the o2 sensor, the coolant temp sensor, the coil packs and all the injectors have been cleaned.

If I turn the car off while it is doing it (while driving) and then turn it back on again...it comes good for a few minutes...then goes crap again.

If I disconnect the plug to the knock sensors, I get an immediate knock sensor code on my scan tool but if I drive it it goes really well all the time....the only problem is when you go to accel...there is a delay for about 2 seconds, then you almost end up in the back seat. Other than that, it goes really good with the knock sensors unplugged. also it has trouble revving over 5500 with them unplugged.

Anyone got any ideas?
