car is a 90 civ hatch, i swapped a b16 in a year ago, the car runs and drives ***** out but it has this strange hesitation between 2000k and 3000rpm in any gear just cruisin slow, its very constant, but as soon as you get over 3000 rpm it clears right off and takes off? wierd, i've checked everything i can think of, also it just kicked a map sensor code, so i replaced it, the check engine light on the dash went out but the ecu is still blinking 3 times at me....? anyone have any thoughts, thanks in advance for any input and yeah the car has had the same hesitation for the last year,lol its driving me nuts tring to figure it out.
