I bought this Camry about a year and a half ago with a check engine light on problem. Erratic idle prompted me to take it in to the Dealer for servicing. Dealer diagnosed code 12 and 41. Recommended replacing the distributor, ignition coiil, plug wires and spark plugs, and throttle positon sensor. Check engine light still remained. Erratic operation still continued with addition of intermittant hard starting. Took it to another auto mechanic. Recommended replacing the distributor again. Mechanic did a check of signals sent from the distributor to the computer controlling idle rpm and fuel delivery. Did a wire harness check. Recommended testing and or rebuilding/replacing the main Engine computer (ECM). Sent ECU out to be repaired/rebuilt. Returned with the problem and some new ones. Car now stalss or dies out intermittently when at a stop. Sent ECU back to the rebuilder. Returned with the same problems. Took car to a local auto diagnostic sun center. Tech diagnosed all systems good with the exception of the computer. Distributor, starting/ignition, sensors, grounds systems and the wire harness circuitry are all doing what they are supposed to do whithin specs. How do I verify or correct this possible computer problem when the repair/rebuild folks say that the computer is fixed?
