Question about 1998 Audi A4
I have a 98 a4 2.4 v6 engine which starts fine when cold but if you try to start the engine when hot it takes longer to start and then fires up really slowly ( almost like its flooded ) and cuts out a lot unless you use high revs when changing gear for the first few minutes.
It is very likely that you are having an air leak. Any uncontrolled air getting into the intake side can cause this problem. Audi is well known for vacuum problems. I was the southern technical specialist for Audi for 6 years. If you have a vacuum test pump you can do some testing yourself but to be honest there are so many little hoses on that engine that you most likely not get to them all. I would suggest you go to your mechanic and see if they can perform a smoke test on the system. Many shops have a tool that can inject smoke (like a smoke machine at the club) into the system and locate the leak rather fast then.
