Engine Performance problem
1989 Toyota pickup 6 cyl Two Wheel Drive Manual 150k miles

erratic miss, almost completely masked on coldstart, becoming worse afterward then better as engine warms. Suspect an injector, how to prove it and then isolate to deal with it? Passes DEQ easily.

Hi there,

Do a scan first and see if the system is detecting a single cylinder miss fire, this will be the best place to start.
