PONTIAC GRAND PRIX RPM PROBLEM

1992 Pontiac Grand Prix

I Have A 1992 Grand Prix And While I Am Driving Down The Road It Will Start Cutting Back And Won’t Go And When I Mash The Gas Petal It Goes All The Way To The Floor And Will Not Even Rev Up And The Brakes Get Hard Or I Won’t Even Have Any Brakes But The Car Is Still Running. The Rpms Go Up To 2 Rpms Then Back To 1 Rpms When Its Just Sitting At A Red Light. It Will Also Start Skipping And Backfires.

Do you have a check engine light?

Have the fuel pressure checked if its within specs and also the MAP and TPS sensors
