Hello, am new here and needs help. My 2003 Pathy showed a Camshaft Actuator and HO2 codes. Please someone tell,are these serious problems? Can I fixthem myselt? Where should I look to fixthem myself. Present the truck shudders and will not speed past 40-50 miles most times. Additionally, I think it is affecting the Auto transmission too, it will go shift from 4 upward.

Early responses will be appreciated.

regards
