Ok i have a B16A2 motor and i have a studdering problem in lower RPM's but it seems Fine after 4000 mostly 1st-3rd gear i have MSD ignition and its been on for a while and i havent had problems in the past.... but anyway this is what ive done so far when the problem occured NEW MSD Cap New OEM Rotor New NGK Spark Plugs, New Wires... after all that its gotten better but it still Bogs my boy said it could be the O2 also my Crank position Sensor isnt hooked up could that be a factor??? thanks in advance...

 

bump... anybody???

 

my o2's just went out... and i'm having the same problem so it could be that...

but the cps could do the same thing.... are you throwing any codes and if so which ones... i mean obviously the one for the cps but are you throwing any other codes
cuz if you have that then we can help you diagnose your problem better

 

thanks... could there be anything else to look at as well?

 

i would just start with the o2's and the crank sensor... after you fix that if you still have the problem see if you are throwing any cel's and if you are diagnose new problem from there...

good luck

 

but would the O2's cause a Bog...?

 

shitty fuel filter, clogged fuel injectors. poor fuel pump (not working well)
