Engine Performance problem
2003 Mazda Protege 4 cyl Front Wheel Drive Manual 77000 miles
My car has started acting up. For the last month or so the engine occasionally starts acting up (frequency has increased in last week or so) Under constant throttle, engine will hesitate and sputter, seems like something's misfiring. During this time, if I put the car in neutral, the rpm's go very low and the car feels like it wants to stall. However, this occurrence doesn't happen all the time, but seems like it occurs once the engine is warmed up. It will come and go randomly, but if I rev the car up that usually fixes it. As of today, check engine light came on, code is P0401, "EGR System Insufficient Flow Detected", but I fear this may be a symptom, not the underlying problem. HELP!
have the same problem?
