I own a 2000 Hyundai Elantra with a 2.0 and an automatic transmission. When I start my car it revs way up unless I tap the gas pedal. While driving the car jerks back and forth like its shifting constantly. There is not any trouble codes to read other than a red air bag light. The car even feels like its shifting when I am going down the highway at 70+ mph. It seems to drive better if I rest my foot on the gas pedal as to give it just enough gas to keep it under load, and not accelerate. I wiggled my MAF sensor and the car revs up slightly then back to normal idle. I am going to clean my MAF sensor and see if that has anything to do with it. I thought there maybe a problem with the transmission so I checked the fluid and it was very low, so I filled it to the correct amount, it didnt fix the problem any tho. I have been searching the internet for ideas and that is how I got the idea to check the MAF sensor.
