i have a 95 civic with a b18b swapped in it. everything works except it sometimes bog at 60-70 mph.it feels like your losing power. step on gas while its bogging will just make it bog more. press gas pedal all the way down and it will finally pass through and it will stop the bogging. it sometime will have white smoke coming out of the exhaust too but only for a short period of time, like 5-10 sec. it will not bog on idle. this is what i replace: fuel pump, dist. rotor and cap, spark plugs, whole catback alone with test pipe (ebay one). my compression test were starting at cyclinder 1-4 165,165,170,170. it seems okay to me and again it doesnt do it all the time. Any idea will help thanks!
