Hi all

My 1999 1.4 16v polo has been giving me problems!

My car used to idle at 800rpm at standstill, now this has increased to 1000rpm.

When i move away the revs do not return to rest when coming to a standstill. They remain around 1000-1500 rpm

Upon start the revs hit 3000rpm and go between 2000 and 3000rpm and do not settle down to normal. Unless I stop the car and restart when they idle at 1000rpm....

Could it be the temperature sensor or need i need to clean the throttle body?
