The "check engine" light came up on our minivan. My wife noticed it was running slightly rough that morning and when the light came on, she was right around the corner of a service station we often use. She drove right in. They told her they didn't have the time to check it out right then but it was safe to drive. She drove it home (less than 4 miles) and it stayed in the garage until I took it in two days later for a thorough check. They told me it would take about an hour but it took about 2 and a half hours. I was told it needed a tune up and I scheduled it for the next day. I couldn't wait any longer. It took about half an hour for the mechanic to put it back together and he assured me it was safe to drive. All the way home, it rode horribly rough. It seemed to get worse as it was going on. It was bucking and jumping with acceleration and didn't get above 30-35 mph. At first, I thought it was just cold but half way home, I realized it was getting worse. I called the shop when I got home and the mechanic told me he "didn't put it together completely." My wife brought it back the next day and it drove the same way (maybe worse). She and my children also noticed a heavy fuel odor that she told the mechanic about. They did the repairs they talked about but check engine light came back on after a week. I took it to a Toyota dealer and they told me the catalytic converter is fried. I have done a significant amount of research about this and all of the mechanics I talk to are convinced that between the diagnostic appointment and the repair work, the 8 miles of driving in the poor condition caused the damage to the catalytic converter. They have told me the wires were not placed replaced correctly when they did the diagnostic check and the 8 miles we drove allowed unburned fuel to be dumped into the catalytic converter and that most likely caused the failure. When I told this to the service station, the told me the Electric Control Module would prevent any such damage. Toyota says it will handle minor amounts of fuel but that the driving condition I described would not be prevented from causing damage. Can you help in sorting this out?
have the same problem?
