I actually had the cat changed during this whole process and I have cleared the computer and unplugged the battery several times and the code always comes back. Dave

But as an update, I took my car to the dealer this week and they said that they ran some diagnostics on the old ECU and the new one that I had put in. The diagnostics showed that they were both bad. I had them put a new one in and the car is now running fine with no codes. Unfortunately, it cost $500 for the new ECU, but I was sick of dealing with the problem and I'm glad that the problem is finally fixed. Thanks again everyone for all of the help, Dave

We just moved this last week and you don't even want to know half of the list of "bad luck" that's happened to us during that whole process, so may I should go buy a lottery ticket just hoping that a run of "good luck" will even it out. But the most frustrating part is that if the ECU I had gotten was fine, then I'd be $800 richer right now. But I guess that's just the way the cookie crumbles and at least my car is finally working again. Dave |
