ok car has been good s far just to nite went for a blast going pretty fast when i came back home the car was ticking over a 1000rpm its been a thats the first time it done that it was ticking over well below that is any idea were to look is there a idle control valve ? or anyother ideas were to look thnak for any help

is your air con on ?

no its off

Had that with mine, faulty temp sensor on top water pipe, check the conection is ok, might be as simple as that mate :)

check the water temp sensor connector is on tight and not dirty on terminals on front water pipe (the bigger of the 2) .Before you go messing with idle screw theres a few things to check 1st or you will be a dog chasing its own tail;)
