HiI was wondering if anyone can help me with a problem I have recently been having with my Audi A4 B5.Recently when I come to traffic lights or any roundabouts my engine seems to idle very badly as its starved of fuel. Most of the time the engine completely cuts out resulting in me to having to start the car up again.When I start the car in the morning it is fine and drives absolutely normal for about 10 minutes. Soon as my temp coolant reaches up half way on my gauge, that's when the cutting out of the engine and really bad idle of the car starts.The few things I have had done to rectify this problemBrand new throttle body replaced & adapted with Vag ComUpper breather pipes removed, cleaned and replacedVacuum pipes replaced as some were damaged.Coolant fully drained and replaced and also had the coolant thermostat replaced.
Lambda sensor replaced - Genuine Audi replacement.
Air Mass flow sensor replaced with a new Hitachi replacement.
What I have also noticed is that when I drive my car in 2nd gear and take the revs up to 5000rpm the car judders and jerks and wont go any higher in the revs. It only seems to do this in the 2nd gear?
Any help would be appreciated on helping me diagnose this problem
Regards
Guv
