so i got this code out of my prelude and the symptoms are the following:
bogging at low rpm <2000
and some rare backfire at the same rpm

i already ran some injector cleaner through the gas with no changes... anyone else have any solutions?

 

Check ur spark plugs, they'll tell u if ur running rich or lean. Knowing if u're running rich or lean will help determine what to check for next.

 

i guess running rich is black crap on them but what about lean?

this is for a 5th gen base model lude just so no one asks

 

ok so took the plugs out and took some pics so here they are from cylinder 1 to 4





basiclt they all black with some white crap on the little arm part

 

they look pretty good dude, that doesn't seem to me to be the problem. slightly lean I would say

I would check to make sure the egr valve isn't stuck open by buildup and that the map sensor is soundly connected, not leaking, etc.

 

got a pic of the location of said components?

 

get a manual for your car, that should be the first step in solving any problem.

 

k well i cleaned out the EGR valve this morning and no change. the valve is working fine. so now im leaning towards getting all the ignition components changed (rotor cap and wires)

anyone else have anhy input?.

 

looks those plugs are rich in the lower rpms and getting leaner in VTEC

I never got a code but when I had my bogging issue it turned out that my cap and rotor had probably never been changed in the 95000 miles the previous owner had it and it all worn away changed that with plugs and wires for good measure and the car was a whole different car.

how does the power feel in the rest of the power band?
do you have any mods?

try and give a lot more info to narrow the problem.

 

just fyi, that code normally comes when the o2 sensor is on its way out.

 

power 3500 and up feels as it should (based on what ive seen so far) and ive changed the 02 sensor with one from an accord i had to lenghten the wires) and no change.
