i would never take something to a place that claimed they couldnt work on a car because it was OBD1. That place needs to go out of business.

A few years ago I had to have one of the main bolts (Control arm maybe? Camber bolt I think?) - had to have it replaced and helicoiled and Nissan had to call around for a mechanic that could work on my 1996.

Now Subaru, bouight a 2007 - got free oil changes from life transferred over, for about 3 oil changes, and then suddenly a $2500 diagnosis for catalytic converters popped up and they offered to do it for that price without labor..

Well, $59 later and a new gas cap and the error cleared and the car runs just fine.
Shysters....

I learn something new everyday on these various model-specific sites! I've never heard of a dealer refusing to work on one of its own models. But, then again, I never take my vehicles to dealerships except for recalls ...

My guess is they're using that as an excuse because they don't want to attempt to fix a botched repair job.

I replaced that with an O'Reilly's MAF sensor which cured the fail-safe mode but the truck still runs rich as I can smell the exhaust and my mpg has dropped. I've looked for vacuum leaks, checked timing, ECU mode 3 gives me a 55 so there are no codes. So I don't know what else to check.

im sure there are a few reasons they didt no want to touch an OBDI system. for one, it would be a total stroke of luck to find a garage that still had the primitive computer system to connect to the consult port. that would be a goldmine.

another one is the amount of legwork, or finger work in this case, required to read diagrams and then go get the part and a test meter and diagnose. we all know that the new cars will tell you everything, including how many times you shook it when you took a leak.

parts being readily available is probably another issue. if you have it torn apart and cant get a needed item, it sits, preventing more money form being made.................i imagine its just a whole combination of things.

whyit, amazingly I did check the wiring continuity on both wires and they had continuity to the ECU. I would think that a bad ground would throw an 'shorted or open' 12 code.

a rough idle or dying is usually the result of an unplugged MAF. when i got my truck, it had a corroded ground on the MAF and it ran horrible. like missing on 3 cylinders rough.

If it's running really rich you might want to make sure the valve that richens the mixture when cold isn't stuck. I disconnected that thing on mine (I live in the south anyway) because it was making mine run rich. It doesn't like cranking when it's below 45F or so without it, but once it's warm it's happy as a lark.

Check the "hot air pickup control" thing in this thread.
