after that time (its basically clockwork) the ECU seems to switch to a different program and it runs like a wet rag after that.

no errors on the dash, i plan on going to a T4 this week and hope if they see a error but the dash has not given any error so far.

i had a simmiar behaviour with a previous car but that was due to a lambda sensor that had a failed heater. but that one only did that when cold, once the exaust heated up it ran normally.

any idea what can cause this behaviour?


edit: read the codes, none were present.

Guess it depends what a wet rag sounds like when it's running.--


Talking about wet rags-----how's your plenum chamber ???


Go look. Might have fish in it.---
