Engine running: https://youtube.com/shorts/_uOF4oSJshM
Me again.
I have a 1996 16v tracker (hacked up and converted to forklift) that I got with a swapped engine.
She starts easily after priming and runs without stalling, but has a rough idle. The second video shows the engine, but doesnt capture the vibration. It's not terrible, but a little too much to call ok. According to scan tool, idling around 800.
Drives at low speed without issue. A little bogging with sudden gas.
No check engine light, and diagnostics show no codes, which I find hard to believe.
Her last bout of non-running was apparently due to bad gas. I switched "tanks", got a new fuel filter, cleaned up the pump screen. It ran after that. FPR was not holding vacuum so I replaced that, but that didn't affect the idle.
Sprayed starter fluid around intake parts to see if that would find a vacuum leak, but no change.
The EGR valve, is that passenger side, by firewall, mounted sideways? I can move the diaphragm, but it's not a thunk, it just moves.
Where is the IAC? ISC?
Thanks,
D
