Default My local Nissan Dealership says NO to '93 Hardbody???

My local Nissan dealership says they won't work on pre-1995 D21 Hardbody trucks. I guess because of the OBD1 system. That seems awfully pansy-ass to me.
So that begs the question - Is there a way I can sniff out a local repair shop that specializes in mid-1990's D21's? Like a nationwide database of Nissan OBD1 friendly repair shops, for example? I'd like to keep trying to fix my rich fuel problem but I think I'm to the point where I'm over my head.

What kind of work are you looking to have done? It's sad that dealers are so reliant on tech that they can't work on cars anymore.

wave of the future, why use your brain when you can just plug in a computer to tell you what's wrong,(sorry, but we rely too much on tech and not enough on ourselves) was that the only dealer in town?

Just drive in to some local independent mechanic shops and ask. You shouldn't be using a dealer anyway for service.

Foul_mouth, the short story is that my friend and I (mostly him) replaced a head gasket on this 93 D21. When started, it ran SUPER rich and was in fail-safe mode. Apparently I destroyed the MAF sensor by sticking a screwdriver down the MAF tube. 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.

I had that problem and it turned out to be the MAF wiring having a bad ground

What does the truck do if you unplug the MAF while running?
