I can't figure out this misfire.
Well here is where I am at with my problem. '99 4runner with 3.4L and it started an occasional misfire on Cyl #3. I say occasional, and I mean every 2 or 3 days, and the misfire only happens for a few minutes and then goes away.
New plugs, no fix. Swapped coil packs 3 and 1 to isolate the problem. Still misfires on 3. So this points me towards the injector. When I ohm tested it today, I touched the probes to the terminals and got a reading of 37 and then it worked its way down to 15.7 and then settled there. I think the 15 is normal, but should be be starting up so high? I've never tested an injector before so maybe that was a foolish question, but I just don't know. Can an injector be bad, even if it ohms properly?
I've been chasing this demon for weeks now and I have two more weeks to figure it out before I am supposed to take the 4runner on a fairly lengthy drive. Can anyone shed any light on this for me, or should I just bite the bullet and take it to a shop and bend over when the bill comes?
