My check engine light came on. i got it checked and it pointed out the O2 sensor and the converters. i changed both of my converters and the car felt a little better. i thought maybe the MAF sensor can be the problem so yesterday i cleaned it w/ this special spray i bought at a parts store. it ran the same when i first started it and then after like 5 minutes it was running better then ever and when i took off it felt like new. after like ten minutes the car went back to its original state and it just started running ritch and ruff like always. my check engine cuts off and comes back off and even sometimes when i come to a complete stop the car turns off. i wanted to know if the MAF sensor was bad or if it was something different?
