B8 A4 weird idle issue
A few months ago my idle started to be a little rough so I cleaned my valves again with the BG services apparatus and it seemed better. A few weeks later it started again so I boost leak tested it. Ended up replacing a leaky PCV assembly. Idle seemed much better again.
Well now it's idling rougher than ever but if I give it enough gas to raise the rpm by 100 or so, it purrs like a kitten. It's almost like my idle rpm's are too low. Even if I turn on the A/C it's better because it raises the idle. Car drives great other than the idle vibrates and rattles the whole car.
Thanks for any help or suggestions!
