Hello guys, I'm new to this and it's my first time on a forum. I really need some help please... I just bought my first mustang. I'm super excited. It's a 2002 Mustang GT V8. 127k miles. There's an issue with it tho. When the mass air flow censor is plugged in, it idols ROUGH, and runs ROUGH! After 3rd RPM it runs perfectly normal. Below that, it runs so bad. But when I plug the mass air flow censors back in, the car will turn over, but will NOT idol or drive. I'm so lost, and don't have much money to spend. I figured this means the mass air flow censor is bad.. My mechanic says no, it's a miss read code. Anyone else have this issue? Any fix?
