I need help! Had a guy replace my serpentine belt and rear center motor mount last week. Since then, when I give it hard throttle, it feels like I am putting on the brakes. If I let off the gas and use easy throttle, it seems to gradually accelerate. I have replaced plugs, wires, coil, thermostat housing, thermostat and upper radiator hose within the last week. I cleaned maf sensor no difference.
It is a manual trans.
When he lifted the motor to replace the mount, could he have knocked a sensor loose? or when he was installing the belt? Car has 118k miles on the clock. I would hate to have to pay dealer 95.00 diagnostic fee. I replaced the fuel filter last year. I will prob just replace it again in case of small obstruction. Don't know where to go from here?
Also replace air filter last month and I have NO CEL!!!
