Yesterday leaving the neighborhood my CEL illuminated, the engine started to sputter and eventually died. After a few minutes the engine would start but die as soon as it started. I eventually got it running and made it home, sputtering the entire way. Scan gave me codes P0121, P0455 and P0442. P0442 and P0455 are both related to the evap emissions system?. Because of P0121 and out of weekend desperation and I replaced the TPS with an Orielly part, cleared the codes and saw no change in the way the vehicle was running. (Mopar TPS is on order). CEL on again immediatly after Orielly TPS change, P1297 which is a MAP code. Decided to clear the code and try one more time, engine ran the same and this time picked up P0340 (camshaft pos. sens) and P1296 (no 5v to MAP sensor).
Is it likely the Mopar TPS will fix the problem? Should I replace the MAP sensor? What else should I do to help diagnose ?
