I believe I'm posting this in the right location..
I have a 1994 fzj80 with around 240k on the clock. On the drive home last night after fueling up running around 75mph the truck started to feel a bit weird like the engine was stumbling. Limping it home the engine would dropped down in rpm frequently under load. When going down a hill letting off the gas the truck would backfire quite a bit.
I checked the engine codes with the results of
1. 24-intake air temperature sensor signal
2. 25- air fuel ratio lean (on since cats were remover)
3. 31-air flow meter signal (vacuum sensor signal)(was told to unplug maf to see if the engine would die)
4. 41-throttle position sensor signal
Does anyone know if there's a fuse that may have blown that would cause those codes? I find it hard to believe that that much stuff would go wrong in that short amount of time. Also what would cause the engine to stumble like that?
