toyota T-100, misfire on number 4 cyl.
1996 Toyota T-100 4x4, 3.4 Liter V-6. Mis-fire on number 4 cylinder. I changed plugs wires and swapped coil packs, still misfires.
It doesnt misfire all the time, somedays not at all. been mis-firing regularly.
I am having the same issue with my 1996 T-100 4X2 2.3 Liter V-6 (222,000 miles). My misfire is on cylinder 3. Did the same things: changed plugs, wires, and switched coil. Still misfires. It pretty much misfires all the time now. The 1st week I noticed it, it would run good and misfire regularly like yours, but now it never fires. Don't know what to do with it next. Sorry I am no help to you. Just letting you know there are others with the same issue recently.
I have the same problem as well on #4 they original told me I had a injector needing replaced so they did and still the same???
1996 Toyota T-100, 3.4 V6 2WD 103,600 miles: Mis-fire on 2 cyl in May 2010. ended up putting in new injector. Drove from MN to AK now September 2010: Miss-fire on 4 cyl - all potential electrical problems looked at. I'm not any help but want to follow this thread if anyone pipes in about a known issue. Thanks!
Guys I had the same problem on my 95 T100 3.4 V6 4WD. I had a misfire on number six. Check your fuel injector. I did the check with the screw driver trick. I could hear is clicking but very soft. Replaced it and no more misfire. Hope this help. The truck now has 310,000 miles on it.
I have a 1995 T100 3.4 4wd with 175k miles on it, replaced all the injectors, plugs (with dual electrode ones), plug wires, and coil, but still having a misfire on cyl #2 and very rough idle, had a compression test done and all is good there, also replaced the fuel filter, I am at my wits end... Does anyone have any opinions? Thanks
