Just bought it, how/where to scan for codes, adapters huh? Just passed smog, but CEL is on, I can't figure out how to pull codes and dies every now and then at a stop, idels loppy, up and down and then perfect/
seems like oil is dirty, but really black and hardly and viscosity, drippy almost. Plenty of pep, when warmed up though seems to want to gasp for air or fuel if you punch it. Sorry out of work would have donated more.

Hi
Locate ECM behind glove box. With key on insert small screwdriver in acces port on ECM. Turn fully clockwise wait 2 sec. Then turn fully counterclockwise. MIL will begin to flash codes. Long flashes first digit of code (.6 sec) Short flash second digit (.3 sec.). Example 3 long flashes followed by 5 short is Code 35. Post codes will advise.
Thanks for donate

I don't want to count flashes, I have a scanner, but it won't connect to this OBD II car and I was told I need a Nissan adapter, nobody know what the name is or where to buy it and OBD II is supposed to by law fit all OBD II cars, whats up? If you can't answer this I gave symptoms and I was hoping to get "What I should check, like a flow chart of sorts.

You have an OBD I system OBD II did not take affect till 1997. So counting flashes is only way short of going to Dealer. Your symptoms could be caused by several things or multiple faults. How are plugs, wires, dist cap, air filter, fuel filter. Fuel pressure and compression test would help. And do flash test then I'll have enough info to diagnose.

I can answer it and I'm not a tech, the code is 0102 and it means the mass air flow sensor is bad, Haynes manual told me quicker than posting here. I am surprised because I came here looking for someone trained and thought I would get the answer. I guess you have to take a chance with these internet deals.
