Car running rough, got codes that said change mass airflow sensor(did that) & car ran a litttle better but didn't accelerate smoothly. Codes also said i needed a camshaft position sensor, changed that got a little better but still continued cutting out while going up or down a hill & still doesn't accelerate smoothly. Other codes said trouble with 02 sensors. Should I replace them or have another scan done. Is there a better diagnostic computer than the Snap On solaris(not sure of spelling).
