Engine Performance problem
1998 Mercury Mystique 6 cyl Front Wheel Drive Automatic 149000 miles
Hello there, my check engine light has come on and I've noticed my MPG has gone way down. I'm pretty sure one thing wrong is my Mass Air Flow Sensor is dirty or bad, as the car dies after running when it's real cold out and hesitates when I step on the gas when going at HWY speeds. Would that cause my MPG to go down as well? Is it easy to replace?
Also, I've notice it jerks real hard when shifting between 1st and 2nd gear, took it in to a shop and they couldn't tell me exactly what it was. Read a few forums and think it could be the Throttle position sensor or the solenoid. Not sure though, any thoughts? Thanks so much!
have the same problem?
