Hey, my engine is running very bad just when it’s cold. almost even goes out and has no power. when it’s warm it’s top. Cold but partly only on 4 paws. Temerature sensors have been changed and has 0,4Ohm resisted when hot is cold less. The familiar sieve in the intake tube is really around and cleaned. False air can actually exclude. Spark plugs, ignition cable, distributor cap, runners have been renewed. I’m now still typing on the injection nozzles, since I found out that the engine starts immediately in the morning and after 10 min drive has to be driven loosely 8-10 sec at érneutem start. Audi can’t make any comunication with the vehicle. The kat should have lost stones that have found a new home in the exhaust system, can it also lie on a clogged exhaust system??? autobahn he still creates 215km/h in the sufu I actually lost everything by therefore also my preparation but now I am at the end?? can help me?
