After days of my calling I was told the DME module was bad. I would have to wait until Monday's office hours, he said, as it was the weekend, but I found that one is $25 to $30 and of course labor. I didn't mind the wait so far or waiting more as I believe it is worth getting the right answer and hey, you can't hold Sunday against them, right? I call Monday- it is now both crankshaft sensors AND the worst part: the entire ECU computer needs replacing. Really? Why, I ask. I got a bunch of half truths about how the computer works with the sensors and they damage each other if bad. I am told the sensors are $195 each and the computer is $2,850! I call another shop and he verifies that true, but this is the top list price new. Also, they bet the diagnosis is wrong and say to get the car. I call and say that I cannot stick, after labor, over three grand into a brand new computer for a 27 year old car and will pay for all I signed for and pick it up. The mechanic from the weekend was the owner, I find, who says he can get a computer for $1000 in the next sentence. The price dropped a grand and a half just like that to keep me from going. He says they neglected to offer me a rebuilt one. I say I just want to settle my bill and he says no, I absolutely must do this for the car to run! I say I will just store it and have another car anyway and want to pay my bill. He says I will also pay him for FOUR DAYS STORAGE then. I go there and the salesman says no, we can't legally charge for storage since WE didn't get around or quote you until now but the owner tries it. He undid the fees/storage on the work order and I paid for the diagnostic time. I get a copy that says ""balance due"". I point out that this shows I am taking the car but still OWE money, not that I paid. It should say ""balance due: $0.00"" . Then I get one that says ""receipt"" and zero due, but I must sign the old work order from days ago that still says work WILL be done. I point out how this is wrong too. Eventually, a truck transports my car to the other shop, which replaces just the sensors (at much less) and amazingly it turns out the computer is just fine! Nothing was wrong with it. The whole deal was just $300 after labor and runs like a top. I am sure high end customers that just hand over a credit card believe they do exceptional work, they probably do, but how many KNOW what they DIDN'T need and paid for it?
