At hwy speeds and on level ground the eng. RPM will go up about 500 RPM's for no reson. Just started on trip of 150 miles only after about 50 to 60 miles into the trip. There are no eng. Codes. Why?
I frist notieced the problem when the care was in cruse and it kept shuting off the cruse like you would tap the breaks. When I got home and used the care later aroud town in city driving had not a problem. Could this be a elec. Problem or a vaccume problem or even just low on fluid?
