Hi, I have a 06 Commander 4X4 I had already changed the gas cap but was still having problems. 3 times to the shop for evap leak. Replaced smog pump 2x's and the sensor 1x now the evap purge solenoid. Constant check engine light ON. Was wondering if anyone else had this same problem? All before 56,000 thousand miles. Today they replaced solenoid and replaced a trans electrical connector. (5) days after replacing the pump again.
