Hi,
I have a problem. Last month I have changed a MAF sensor in my Volvo S40 1,6 2000, because I was unable to get higher rates then 3000. now it is fine. But I have very opposite problem. When I start the engine, rates are 1100 and when it gets warm my rates drop to 600. And when I run and slow down before crossroad and than try to accelerate from cca 1400 rpm, my car is jumping and doesn´t want to go. Thanks for any advice

Hi, Go parts

It is not my problem, this rough idle.
My idle rates are steady. With cold engine 1100 rpm and when the engine is warm it is 600 rpm. Rates are not jumping up and down. MY problem is that rates drop down when engine get warm. Thanks
