rover 25 idle help
So I am new here and can not find a direct answer so far I have an impression 25 1.4 2003, I have just had the head gasket replaced after it went a month ago.
Since then the car has been idling at 1200-1600, the warmer it gets the higher it idles. it has already had the idle control valve and the map sensor replaced (the map sensor had blown and needed replacing)
What is odd is sometimes, more so when the car is at running temp when I rev it above 4000 it will stick and what is really odd is when I turn on the air con the revs will drop even if it sticks at the 4000.
I only have a loss of power when the engine is cold, once running there is no loss so not sure what to do, was thinking it might be that the throttle body needs a bit of a clean
I am racking my head around this, anyone else every come across this?
