i was driving on the interstate when i downshifted to 5th and the car sounded louder but seemed to run fine. 10 mins later when i got off the interstate the car would not idle and just died. tried to start and heard a loud noise coming from passenger side of motor. could not see anything obvease. car would not start. it's like the timing belt skipped a tooth? there was no smoke coming from the tailpipe. no cel. but checked codes anyway. p0346 and p0341 cps. i replaced the timing belt and every other part on the front of the motor including the starter and alternator about 2000 miles ago. please help
