Default Starting problem

1998 Audi A4 2.8L

I have problem with the car starting when engine is warm, absolutely no problem from cold start. If anyone has experienced a similar problem and has a potential diagnosis I would appreciate the help.

Default Vague post of the day

Any amount of details, recent work, what temp range are you talking about, etc would help *a lot*.

Coolant temperature sensor is my first guess, regardless of which engine.

Seems that part is having a very high rate of failure as of the late.

Default Had like problem last year was sticking plate on throttle body ,cleaned,fixed

Would start cold and fast idle and other circuits would keep car running after warm up car would almost stall at lights. Hot start car wouldn't stay running unless foot was on pedal and stumbled ,stalled intermittently . Cleaned throttle body with spray cleaner and cured the illness.

Default It could be the starter itself. Bad solenoids tend to stick when hot. Wait, I have no idea what

kind of starting problem you have. As Nate mentioned, more detail is needed.

Does it crank at all?
Does it crank and doesn't fire?
Does it crank, fire then die?
Does it crank, fire, idle, and then when you start driving, it dies?
Is it cranky?
