“Well I own a 1999 Pontiac Grand Am se coupe, and I noticed about two months ago at 50-60 MPH (or 2000 rpms), the cars speed and rpms would decrease about 2 MPH and the rpms would decrease about 500 rpms, then it would return and it would do this every time I was at that speed, also now when I accelerate to 60 and if I let the car decrease speed the temp gauge would skyrocket and after about 1/8 a mile it wouldn't let me increase speed along with that my electric fans in the car have never engaged, I love this car and I don't want to get rid of it. …”
