928 S4 idle surging only on hot start
I have been having an issue with my 88 S4 where the idle surges only on hot starts and will sometimes die out if I do not hold the throttle. When the engine is cold it fires right up and idles perfectly. The MAF was replaced a couple of years back and I replaced one of the fuel pressure regulators as it was leaking. Any ideas what else it may be?
