Check Engine light on changed the front o2 sensor and rear O2 sensor unhooked battery for 30 mins. Check engine light went out for 30 miles but as soon as I start her back up the lights back on and the motor wants to miss alittle bit. As soon as the light comes back on I lose enough power to notice. Any suggestions. Had the computer check done and it gave a code to the cam shaft sensor but no one seems to know where or what that is.
