okay that was a fail. no putty road for me.
Some details
Car C34 s2 rs4s - stock in the engine bay.
stalling at idle, hunts around, splutters , then dies. If left for 5 min restarts. if the revs are kept up , no problem.
I have changed the fuel filter
Changed the air filter.
Didn't do the afm today as I have to go out. Do people think this could be the cause? will try tomorrow morning.
The above guide for aac clean is for a r33, and the neo appears to be different, plus I'm not comfortable yet doing this job. SO it's off the mechanic because I love giving them all my money.
