Hey, i have a 1994 civic VTI (B16a2) and have noticed a problem over the last couple of days. Ive had the car for over a year and had no problems... untill now. Heres the problem, when driving (out of vtec before 5500rpm) at a steady pace, if you give it a slight bit more gas the car kinda bogs for a while then picks up normally, it bogs intermitantly and for differant amounts of time (like 1-10secs) if you give it full gas it seems to be fine everytime, and if it bogs and you give it full gas it overcomes it straight away. I changed the fuel filter, put fuel cleaner though it, cleaned the plugs and checked the dizzy and plugs, but its still doing it.
could it be the EGR valve ?
does mine have one and were is it?
or could it be the ICV? i have noticed sumtimes the revs drop to 500rpm then jump up to 800rpm again when you brake, and have been told the ICV are prone to go on the old hondas.

Thanks for any help
