OK IM GOING THROUGH TODAY TO SEE WHAT THE DEAL IS

I HAVE A B20 SWAP ITS BEEN RUNNING GREAT JUST RECENTLY
AT LOW SPEEDS IT BOGGS OUT BUT WHEN I STEP ON THE GAS ALL THE WAS SPEED PICKS UP HELP HELP

just changed spark plugs
still bogging a little bit

than I reset the dizzy all the way back
still boggs

that the rpms go up and down between 800rpm and 1500

what are your thoughts on this?

 

I have seen that before when your off a tooth or jumped a tooth on the t-belt.

 

ok when Im driving it she bogs at low speeds but when the check engine light come on it runs perfest no boggs nothin I need to check the ECU code its pushing out today

 

Could be your o2 sensor...
