Bad coolant temp sensor?

Apologies for digging up this old topic, but I didn't want to create a new one for the same problem.

Question to the topic starter: Has your problem been solved, and what did you have to do to solve it, was it a bad coolant temperature sensor?

Hmm... looks like the topic starter hasn't been here anymore since September last year.

Anyone else have a clue? I have already changed the MAF sensor. Next on my list are the coolant temperature sensor followed by the fuel pressure regulator (not sure what that is in English), but I'm not sure that's the right way to go. Looking forward to any advice
