I have a weird fault with my r32 gts t. Sometimes it runs sweet. Then other times it reaching around 2500 rpm and it runs very lumpy and rough. and it bounces up and down a 1000 rpm. I had it checked over and no faults can be found. I VE CHANGED EVERYTHING and still cant find the fault.
Has anyone else had anything like this?
Cheers

Kind of hard to make out what you're trying to describe, but have you checked the AFM? The coils breaking down can make it run rough too.

afm

Im not sure if AFM has been checked but I had to replace one of the coils because it was failing. Its a weird fault and very difficult to decsribe.

Sound like a AFM fault. Has the ecu been checked for fault codes? Somtimes a AFM fault will not register as a fault but if the diagnostics equipment can read realtime data it may be worth checking the afm voltage when the fault happens.
