1996 4runner cylinder 6 misfire
I have a 1996 4runner 4wd that have a cylinder 6 misfire. I have changed spark plugs and wire and #6 fuel injector but problem still there. I have swapped coil packs too. I have used fuel injecotr cleaner and switched to super unleaded gas but none worked. don't know what to do next.

Are there any trouble codes, i.e. check engine light?
I would have a compression test done to try and eliminate a bad gasket on the intake manifold.

Hint.......A vacuum leak will affect the closest cylinder, so look for pinched , burnt, or otherwise damaged hoses at the BACK of the manifold.

there is still an engine light on and i pulled a p306 code ( cylinder 6 misfire ) on my obd. compression test was done on all cylinders and passed. both gaskets on intake manifold also been replaced. i will check any vacuum leaks / pinched airlines but if anybody can give more suggestions / troubleshooting technics, i will greatly appreciate it.

I have checked airlines for leaks and none found. Have reseated #6 fuel injector power connector and none seems to work. I'm at the end of the road, I think it is time to take it to a mechanic.

did you try a noid light in the No 6 injector wire connector?
also try useing a propane torch with a vac hose hooked up instead of the flame difuser to place propane in the areas around the intake and head sealing area to check for vac leaks. this will help isolate vac leaks especially if you use a short piece of steel brake line (about 12in.) to help you to pinpoint placement. works much better than squirting oil on the surfaces.
remember murphy was an optimist.
