Exhaust Or Afm

[bugz]

When i give 'er some revs in neutral the engine stutters for a second or two till the revs build up.

I have gone round tightening everything i can think of.

I have found a small (20mm) long open section where the zorst guy hasnt welded the resonator up properly. Also, when i rev i think i can hear a whistling sound from the AFM which is located just after the FMIC and prior to Greddy plenum.

Question is....which one or both?

Any ideas

Thanks

Well exhaust you should weld up either way.

It does potentially sound AFM related, but the AFM 'should' play up all the time. Not just in neutral with a little free-rev...

It should misbehave off load/underload/intermittent for both etc until it gets worse and worse (thats how mine failed)

Could also be TPS perhaps not working correctly IMO... more likely TPS than AFM

Yep, exhaust getting sorted tomorrow.

Think you're right re: TPS because once revs are over 2k she goes like a rocket till redline with no signs of boost loss, missfire, ignition retard etc

^^ well with that info then even less-so AFM
