My car runs real rough. Almost as if its the transmission. Wont shift into gear right away, I have to play with gears. Engine light comes on, runs real rough. Speedometer does not work mileage does not change. I purchased car from Auto Auction, so I have no history on it. Took it for Emissions test and my car failed Emissions test for code P0500 Vehicle Speed Sensor A and P1131 O2 Sensor. O2 sensor seems like wont be a problem, but how do I find out which Speed Sensor is needed. Machine at mechanic shop did not provide info, machanic advsd he will need to get under vehicle to check for this additional charge. I just want to buy the part and pay someone to put it on. Please help!
