Car Forum / Honda Cars / June 200693 Accord hard only running on two cylinders
My 93 accord is only running on the #2 and #4 cylinders. The problem started with difficult starts in the mornings (I live in Hawaii...don't think this counts as a cold start) and it would be even more difficult to start after being parked in the sun for a while. After getting started, it would idle really rough - like it is doing full time now- but would eventually start idling normally after about 15-30 seconds. The problem got progressively worse with the strong fuel odor at each attempt to the point where it would not start. After noticing a leak around the injector for the #2 cylinder, I salvaged 4 jets from a 92 Accord soaked them in Fuel injector cleaner for a couple hours and fitted them to my 93 Accord. Now It is still very hard to start, and when it does, I can take off the #2 and #4 plug wires and it will not make a difference in the way the car idles (rough). I changed the spark plugs/ wires, distributor cap, rotor all within this month, though I have noticed a gouge in one of the contact post inside the distributor cap. Can anyone offer some insight on how to overcome these issues? I have soaked the 4 original injectors in injector cleaner and I am thinking about putting them back on, however after fitting the straw-like nozzle from a can of compressed air over the needle like tip at the bottom of the jets in attempt to blow out any residual cleaning solution, I realized the air passed freely through two of the jets but did not through the other two. Should I be concerned about this? Thanks Rasta > I changed the spark plugs/ wires, distributor cap, rotor all within > this month, though I have noticed a gouge in one of the contact post > inside the distributor cap. how are the bearings inside the distributor? any red dust? excessive play in the rotor? a gouge would indicate somethings hitting something it shouldnt be. > > I changed the spark plugs/ wires, distributor cap, rotor all within > > this month, though I have noticed a gouge in one of the contact post [quoted text clipped - 3 lines] > play in the rotor? a gouge would indicate somethings hitting something > it shouldnt be. There is minimal rotatitional play but none left/righ or up/down. The inside of the distributor looks brand new, the igniter was also replaced within the last 6 months. I would like to imagine that the gouge was made becuse the screw which secures the underside of the distributor was loose for a few days, in any event the sparks are being deliverd to the plugswith no further action. > My 93 accord is only running on the #2 and #4 cylinders.

Your car has a normal distributor. ib is referring to wasted-spark ignition with no distributor.

I've beeen to Hawaii and it's never 190F there. > and it would be > even more difficult to start after being parked in the sun for a while. [quoted text clipped - 11 lines] > this month, though I have noticed a gouge in one of the contact post > inside the distributor cap. With the engine running, pull each spark plug wire in turn and hold it close to a metal engine part. Do you consistently see and hear a yellow spark on each wire? (Holding the wire will hurt until the spark has someplace to go). If you can't keep the motor running, have a helper crank it while you hold the wire. Try to do this at night, to make it easier to see the spark. > Can anyone offer some insight on how to overcome these issues? > [quoted text clipped - 4 lines] > solution, I realized the air passed freely through two of the jets but > did not through the other two. Should I be concerned about this? You mean the spray passed all the way into the injector? This should *not* be possible. They are sealed shut when not electrically activated. Please clarify.

I have seen rockers grossly out of adjustment or worn to the point of no valve action - which fits your description of gradually getting worse. > TeGGeR® ...The answer to your question is yes, the air went all the > way through two of the four injector. that is why I wasnt sure which [quoted text clipped - 49 lines] >>The Unofficial Honda/Acura FAQ >>www.tegger.com/hondafaq/ > TeGGeR® ...The answer to your question is yes, the air went all the > way through two of the four injector. that is why I wasnt sure which > were good and which were bad. The two where air goes all the way through, something is SERIOUSLY wrong with them. This may be your whole problem. Go to the wreckers and get two off a wreck. I got four recently, for $10 per injector. SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ > My 93 accord is only running on the #2 and #4 cylinders.

I am loosing some coolant but I know the radiator cap needs to be repalced I can see the vapors coming from the cap when it gets hot. > > My 93 accord is only running on the #2 and #4 cylinders.

[leakage of the radiator cap may be due to excess gas pressure.] i just had the same problems on my civic and misfire on first start that gradually disappeared after a few seconds was what you'd expect from moisture in the cylinder. honda often don't give the usual head gasket symptoms like mayonnaise under the oil cap or oil in the coolant. >>>My 93 accord is only running on the #2 and #4 cylinders.
