Well ive cleaned the TB with seafoam 2wice now, 2 bottles of fuel injector cleaner (2 tanks of gas) Plugs, coolant, grounds, new fuel filter, tried 3 different intake setups new spark wires....and still same problem. Sometimes only SOMETIMES does it work like it should, but thats only maybe once every month or so for like a car ride of durration. What happens is that i can accellerate fine with maybe 1/4 throttle but when i increase it to 1/2 or 3/4 throttle it just bogs or RPMs dont really increase that fast and kinda studders lightly. It worked for like 3 days after i put seafoam in the gas tank. No matter what RPM or speed or gear, the second i punch it, nothing but noise. NO CELs and no vacum leaks as far as i know. Ive spend tonz of money trying to fix this problem.

was thinking it was the sensors on teh TB but theres no CEL so i dunno just bought one off ebay (97 EX TB) for $30. But it seems as if somebody completely covers the intake when i floor it...hmm have 3 different filters ive tried including K&N (i have a CAI). anybody know anything? please help me out THANKS!

Check your timing. If need be, set back to stock ( assuming you are talking about an almost completely stock motor).

How does it run with the engine cold or full throttle? If its ok during these, its probably the o2 sensor.

When it first starts up, its a little better, and then after about 10 minutes of driving ohh man is it horrible. Takes me about 1 minute to go from 60-80 in 5th doing 3krpms.....today was on the highway and could hardly make it up a hill, hardly!

but full throttle no, it seems as if its sucking a **** load of air in and farting it all out without speeding up. I assume when you punch the gas it moves right? sound like a misfire? there is a delay when the engine is warm when i quickly press the gas, and you can hear a very very loud but very short whoosh comming from the CAI filter.
