1991 FJ80 with 245,000mi. My issue was present before and after I recently did my injectors. When idling for a minute or 2 the engine starts to misfire, lope, and generally "run rough". A quick press on the go pedal will make the engine run correct for about 5 seconds then run poorly again after that. Smoke test shows no vacuum leaks.
Trucks has 6 cleaned, re-screened, and verified OEM injectors
New AFM
Brand new fuel filter
2 year old fuel pump(even though the age could mean nothing cause we have all seen faulty 'new parts')
