Ok so I picked up this 1990 Toyota pickup for $700 and I have lowering, body and wheel plans, BUT cylinder 1 has a constant misfire that I cant figure out.
It's misfiring at idle and kind of smooths out when I accelerate but still misfires (based on my Subaru sounding exhaust note).
So far ive changed plugs wires cap and rotor and I did a compression test here's mu results:
Cyl.1- 165
Cyl.2-162
Cyl.3-165
Cyl.4-168
Drove exactly the same after ignition parts where replaced. I'm thinking it could be a fuel injector on cyl.1 since the plug looked clean compared to the others. Before I swap injectors I was thinking if I could run some fuel injector cleaner and possibly get that first one working again? Also the plugs were pretty burnt up when I pulled them out and the first plug was slightly wet.
Also any ideas besides fuel injectors?
Here's a pic of the truck just to keep it exciting lol.
