I hope you can help. I have been having this problem with my 2002 Saturn SL1 mileage 58,850. The problem only occurs after the vehicle has warmed up fully. I have a major drop in power and i can feel it in the gas pedal. Most of the time just to accelerate i have to put the pedal to the floor and it is still not a quick response. Also, when i'm starting from a stopped position there is a brief moment where it seems like the car will stall then be fine. i've replaced the plugs, coil packs, air filter, but i'm too broke to bring it to a shop. any advice will be helpful advice.
