you might need to do a compression test. i talked to my mechanic today as a matter of fact and he told me if I had compression problems, then it would be missing. since you changed out all that other stuff i would give that a try.

did it start missing immediately after you changed out all the wires, plugs, and such? if so, maybe you have a wire crossed or something.

maybe somebody else will chime in with some better answers but this is all i could think of this late in the evening.

Let's get some more info. I'm assuming that by, 'hot' you mean normal operating temp. Or are you overheating? Have you switched to a cheaper gas recently? If I run the cheap stuff, I get a miss. Also, where is the miss in the rpm range? Or does it miss all the way through?

Could be many things; have you pulled the codes?

When it starts to miss, spray a little carb cleaner at the bottom of each injector. Mine was missing after warm up and that's how I found I had injector O ring leaking.

can not spray carb cleaner on the left side to the injectors..they are under the headsor rather a bar that runs on top of the head..4runnerx3...also how do u pull the codes tnrabbit and chickenlover..it misses all the way through.

As they said, switch to 91 octane if you have'nt done so, 87 octane will ping and miss at some circumstance..., and did you screw your spark plugs all the way in?
