Mazda CX-7 Surging During Acceleration
Recently had a problem with the engine surging/losing-power during acceleration. Felt at first like a transmission problem as if the tranny was slipping, but with no bang. Ran fine at both idle and cruising speeds, but struggled to accelerate. CEL never came on.
Went to the dealer and was told their is a service notice from the manufacturer that the Oxygen sensors are not reading properly. Technician with computer took the vehicle out and confirmed that one of my Oxygen sensors is not reading correctly, but is within spec's (?) so their is a loss of performance but no CEL. Car runs great again. Not under warranty unfortunatley so cost $300+.
