i have a 93 civic hatch with a b16. the problem : sometimes my car feels like it doesnt want to drive. i press the gas and it doesnt do nothing, then bam it kicks in hard then bogs out again. i changed the rotor and cap on the dizzy and itstill does it. i think it could be the map sensor but there is no check engine light. i was having problems with the sensor (i know because the check engine light came on)but then i took it out cleaned the clip and the check engine never came on again. please help
