i have 100K miles on it and i dont have any modifications.
also i never rev the motor before it hits 3 bars and it happens at 3-5 rpm not while in vtec.
i dunno if this has anything to do with it but a month or two ago i replaced the air filter and i forgot to put the air box cover on it so the filter is exposed. never could find the cover again.
but i'll try the injection cleaner and stuff and let you guys know

new plugs, new fuel filter, new air filter (this does wonders), valve adjustment, new clutch and flywheel. it could definitely be the clutch slipping on the way to die.

after reading some another post i'm thinking it might be bad gas. i put some octane booster in it and it seems to run better. i'm thinking of syphoning the gas out and refilling it to see if cures the problem.

you now make the 4th confirmed case of sudden detrimental performance, almost assuredly caused by contaminated gasoline. Where did you get the gas from that was in the car when it started to run bad? I got mine from Citgo...

I have THE EXACT problem and have been trying to figure it out for months. I did the injector cleaner, took my throttle body apart...cleaned the hell out of that, and did a tune up. I don't think the plugs or the filter was replaced.
Also, i've been told on multiple occasions that it's probably my clutch. What makes me hesitant to believe this is that ever since it got cold out it's been running perfect. The couple days here and there that its gotten warm it's started to act up again. The last three to four days it's been above 70 degrees and it's acted up all four days. So i'm pretty convinced that whatever is going on is heat related. Heat soak? Catalytic converter?

What exactly is heat soak? Also, if it was the clutch...would it be likely that it would go from being terrible one week to fine the other? Seems like if the clutch was going bad it wouldn't fix itself...but I guess the temperature has something to do with it. Going on seven months now and still no luck.

Heat soak is when the air in the intake stream gets heated to the point that the performance loss is noticeable, but usually only at launches until the heated air has been consumed and replaced by fresher ambient air.

ok so the bogging stopped now when i refilled the tank. now it just seems like i've lost some power throughout the whole powerband. it feels like my clutch is a lot softer now doesnt seem to grab as hard as it used to. thinking my clutch is on the verge of going out. any input?
