I have a 1998 Chevy Malibu when I start the car up it starts fine but when I start to drive I try to press the gas like normal and my RPM goes up but my car is going like 10-15 miles and my MPH doesn't even work at all. Then under the car it sounds like the car wants to go but it acts as if I am stuck in mud or snow and if the RPM is at 4 for like a min. the car will jerk and still do 10-15 miles still. I took it back 2 the shop where I got the car from they told me I need the O2 Sensor changed, but my brother told me its the transmission so somebody please help me!!!!
