how about some injector cleaner in the gasoline? Or changing the fuel filter at least... you didn't list that.

What the mechanic is doing is clearing the ECU memory. If you didn't do that after the tune up, that very well may be the problem.

ok cahnged the fuel filter, and reset the ecu.....no light yet will see what happens now...

ok now thats Plugs, Wires, Cap, Rotor, Oil Change, Valve cover gasket, Tightend Belt, New Fuel Filter, Cleaned Intake Filter, Diffrent type of gas...

I think thats a decent 100K tuneup that should shut off that engine light?

Wait, timming belt...hmm how much are those???

the only hard part is getting the pulley bolt off. You'll either need an impact wrench (and sometime that doesn't work unless it's a nice quality one) OR a big ass flat-head screwdriver and a friend to jam it in the flywheel under the car while you take a breaker bar to the pulley bolt.

Other than that, it's not very hard.

you might, just might want to have a honda dealership check your ECU. if what you say is true, and it is running like a champ, then you are NOT misfiring, especially if the codes are for not one, but TWO cylinders. just my $.02

You need to start with the basics. Fuel, spark, compression. Are you getting fuel to the cylinders. You can use a long screw driver to listen to the injectors as the car is running. Put the end on the injector and your ear on the handle. Make sure they are all sounding the same. Also you may have a clogged or restricted injector. Use some injector clean to help that out. I like Techron use it on a 1/2 tank. It does wonders. For spark get a cheap spark tester and test all the wires. Make sure they jump a good size gap. And last but not least check your compression. Your computer uses the crank and cam sensors to detect the missfire. It isn't always correct on the cylinder number. Sometimes it's off one in the firing order.

Try that stuff it you can't figure it out I'd take it to a shop and let them deal with it.

Well thx for the info, really do appreciate it....well ive done everything except, listin to the injectors, and spark tester thing, ive kinda done a spark test in my own stupid way, but this is really weird... You think its to maybe more of a serious point? Like sticking vlave, warped head, something more serious that just going to worrsen, well ill just have to keep taking your guys advice, and I have been doing everything you guys have told me, so im still looking toward the light at the tunnel.... Maybe it is honda dealer time..., but shit i would think i woudl feel something like this happenind, at idle or something, cause its seems to run fantastic, EXCEPT! now that i remember, sometimes when im driveing i throw it in nutural the car wants to die, goes down to 100-200RPM, car shakes and it brings itself back up...
