That's because, as I mentioned earlier in the thread, the first thing done was replacing the long block at customer request, it ran the same on both long blocks. Okay progress and success. Found out that the Cardone AFM that summit sells is NOT for the 3FE it's for a Ford/Mazda engine. (Even...

In the name of preserving information, the Cardone reman AFMs are, apparently, crap. The one that came in on the vehicle, as well as 2 more are these Cardone parts. Another one should be here Monday, but its all that can be found that is in stock, thru Summit. Of the 3 "identical" parts used...

I've read about ground issues as well, all the grounds I can find are clean and tight. Tho I'm still convinced that the AFM is part of this issue because so far both AFMs I've had failed their bench tests. If I can ask what were the specifics of your ground issue?

Looks like we get to play parts merry go round here. Remanned MAF from Summit showed up today. Engine runs a hair better but still rich, still throwing code 31. When doing FSM diagnostics this time E2 to VS is 48 ohms. E2 to VC is 52 ohms. Spec is 200-600 ohms. Where can I find a NEW afm and...

Progress, pulled the black cap off the AFM. With engine idling the dial is way over towards the + sign. With engine idling if I move the dial it makes no difference in running condition. With engine off, AFM unplugged and checking resistence on AFM terminals E2 to VS read nearly triple the ohms...

Okay with the help from you guys and of your service manuals I found that TPS was not installed properly being that it wasn’t lined up with the prongs on the throttle correctly. Put the new TPS back on and used the feeler gauges and checked resistence etc. Runs better and TPS code is now gone...

I had read about the TPS adjustment being fairly sensative, but can't find any documentation on how to properly adjust and what the readings should be. Perhaps the FSM and this will help with that. I smoke tested the engine 3 times now and paid special attention to the intake hose between AFM...

Hello. I'm new here. I have been working on vehicles most of my life, and currently do it for a living and holding 1 ASE cert (A4). I personally own a 1988 Pathfinder 4x4 and love going out on a good trail. More about that some other time. Got doozy in the shop right now, a 92 FJ80 with the 3FE...
