At the end of my rope, this is the last ditch effort before I haul it to the dealer!
1994 FZJ80.
This issue only occurs when the vehicle has sat for more than about 30 minutes.
Upon cranking- very rough idle. Then when driving, slow acceleration, low power, surging, etc.
Then, all of a sudden after a couple of minutes of driving, it’s as if the engine literally comes to life!
There’s a big surge of power, and the vehicle is running perfectly fine.
I can’t stress it enough- in a split second it will go from sputtering like it’s about to die to running and idling totally normally.
I have replaced the VAFsensor, O2 sensors, cleaned PVC valve, cleaned IAC valve, checked the timing, nothing has really worked.
Only code that is showing is code 26, but I’ve had that code, intermittently for a while
Any ideas?
