Hi. My car has been acting-up sense I had a problem with the battery. It leaked acid on the positive side, so I changed it. A couple of times I had to jump the battery start the car with the old battery. During this time and after I got the new one the car hesitates, doesn't have the same power it used to and it runs rough. I've changed the air filter, the fuel filter, the engine oil. I've checked the alternator, it'* working fine. A mechanic and I scanned it for codes and it doesn't show any of them; but he did notice the car is slow, that it hesitates on cold starts and up hill. The only thing that seems to help is if I unplug the MAF sensor, the car gets its power back and runs smoothly. Does this mean the sensor is bad even thou it'* not giving out a code? Could it be the main computer? What else could be wrong?
Please help! :(
