So i have a 99 ex civic and it bogs when i take of normal so i have to pump the gas pedal a bit for it to go.it only does it sometimes.so i did an oil change.spark plugs,wires.valve cover gasket set. Changed all that. But it still did it.so i read up a few threads and from the info i gathered it said to change the cap and rotor so i did. BINGO IT STOPPED BOGGING FOR A WHOLE DAY.So i tought i had fixed the problem but i was wrong,it started doing it again. What can it be ???should i replace the ignotion coil ?

do you have a check engine light on? if you do check the codes could possibly be a o2 sensor
