Last week my car started giving a jerk while driving and when u go to press the gas it will jerk again and then it stalls. It is really hard to start after it stalls.. but once I get it started it is fine.. when it just sits while running the rpm runs from 1 to 1/hallf. The service engine light is on and while it is stalling the battery and oil picture come on. But when I get it started the lights are not on except service engine is on and now my abs and trac off are on.. when the car is on cruise control it drives fine.. the code reads p0102

Don't worry about the warning lights when engine stalls as that is just the bulb check mode. Service engine while it's running is storing your code of a malfunction of course as it shouldn't be stalling. I'd be checking for fuel pressure while this is happening and for any vacuum leaks that will toss out codes, T

I just did? Check for fuel pressure as any malfunction can throw codes. Codes are a direction to aim not going to tell you something is unplugged or a vacuum leak but the improper info to car's computer will be wrong so it will throw codes, T

You have a "Mass Air Flow" sensor circuit problem and your symptoms match that. Likely a bad MAF but it could also have problems in other parts of the MAF circuit and should be diagnosed properly. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
