Okay fathom this one out...

[Hammy]

Car's great, love it to bits, but I have this niggle which I would like to fathom out.

Starts okay, although a little lumpy when idling.  Need to get it tuned etc....

But the problem is.. Once it is warm and I stop at the gas station etc.. When I get back in and start it up it revs to like 2k rpm and holds for approx 30secs before dropping.  This is very annoying as the car is already warmed up and knows it is warm, but when I start it again for some reason it thinks its cold again...

Any ideas where to look to cure it please ?

Thanks

Faulty coolant temperature sensor?

[Hammy]

Could be.... Hopefully if the weather is good tomorrow *crosses fingers* I will be able to take a look at it.

Changing hydro mount and explansion tank tomorrow if the weathers fine and then move on to the heated rear window and temp sensor

Thanks for the tip

Paul..
