i'm having a problem with my 98 accord lx. it's been bogging lately so i went ahead and did a tune up. i've notice after changing the plugs, i could pull any of the ignition wire off one at a time and it still manages to idle - except for the number two plug. everytime i pull that one, it would imediately stall. is there any reason why only this cylinder acts this way? any suggestion if this has anything to do with the bogging?

If the car runs OK w/ all 4 wires connected, I wouldn't be too concerned. It's likely something to do w/ engine balance and timing of the dead #2 cylinder which increases load beyond ability of remaining cylinders to maintain idle.

Does the "bogging" problem occur under moderate acceleration w/ a sensation of engine gasping for air and failing to accelerate, particularly from 1800 rpm and above?

If yes, this is symptom of blocked EGR ports. See following post:

Good Luck

 

the bogging only happens when cold and in lower rpm's (under 1000rpm). once it bogs for about 2 seconds after you step on the gas, everything seems normal again and the car accelerates fine. it is throwing a code 45 but i haven't had any luck finding out what that is but for civics that is for "fuel too rich or too lean" which would make sense considering what it's doing. i'm wondering what could possibly cause that.

 

Code 45 is too lean mixture. This suggests an air leak somewhere in the intake system; vacuum line loose or damaged, intake manifold lead, cold start air bypass stuck open or other. Look for an intake leak by spraying throttle body cleaner at likely spots w/ engine idling. If you hear an increase in engine speed, you've found the leak.

Once engine warms, the o2 sensor and engine controller may be able to compensate for the overlean condition which may explain why the problem disappears once engine is warm.

good luck

 

im having the same problem with my accord. it starts and idles ok...but when i gas it nothing, it bogs, hesitates, shakes until 4k then it revs normal.
I've checked everything, timing is perfect. Cleaned the injectors and throttle body. checked the wires. All OK.
The plugs are white and dry when i take them out...so is it too lean? I'm leaning toward a bad fuel pump. Maybe its not gettting enough fuel pressure but I'm not sure.

Maybe someone will suggest some stuff to look at.

NO CEL either

 

i took mine in to presision tune and they did recommend a new fuel pump too but i didn't think that would be it because it either works of it doesn't, right? and plus my plugs doesn't show any signs of being too rich or too lean. i'm stumped too...

 

Did they say the fuel pressure was out of specs? If yes, then I would first replace fuel filter and recheck. I agree that fuel pump failing is much less likely, but possible.

An engine may run w/ fuel pressure just out of spec, but could cause drivability issues. Fuel pressure regulator could be a cause of your problem. They sometimes fail w/ diaphragm rupturing. This allows fuel to be pulled into engine through the vacuum line to the fuel pressure regulator. You can check by pulling vacuum line and sniffing for gas. If strong odor of gas or wet w/ gas, you have a problem.

good luck

 

Hey... I had a problem with my accord also... One make sure you have coolent in your car... Make sure your fuel line is Clean and is shooting out the right amount.. If not then check your fuel pump/Filter.. Another thing to make sure of is that you have the right spark.. I got performance wires and coil wire... After that my car was getting TOO MUCH spark and it would bogg way down.. There are many possibilitis to this.. You just have to do trial and error..
