Why is my 2001 Pontiac grand dam rpm going up and down as I acclerate?

Asked by Nov 29, 2016 at 04:51 PM about the 2001 Pontiac Grand Am GT

Question type: Maintenance & Repair

It's shooting out a cylinder 1 misfire code and the antilock break light is
on. The track off light stays on also.

Most likely the misfiring is causing the RPM fluctuations. I'd suggest a tune up (new spark plugs and new spark plug wires) if your Grand Am has over 100,000 miles on it and you don't know if it's ever been tuned up before. As for the ABS and trac off lights it's probably a bad hub bearing assembly. The ABS wheel sensors are incorporated into the hub bearing assembly and frequently fail. This will also disable the traction control system because the two systems work together. HTH. -Jim
