I own a 1998 Honda Civic Dx (automatic trans.), it has over 184K miles. I decided to change the oil last Friday (7/10/15).Instead of putting 5w-30, I unknowingly put in 10w-30. My car didn’t show any signs or symptoms at first until the following Tuesday (7/14/15) when on my way to work, I started having idling problems. Once I realized that my car wasn’t acting the way it should, I pulled over at a vacant parking lot by my job and checked the fluid levels. Not only did I put in the wrong motor oil, the dipstick indicated that I added too much. So I drained the excess amount and test drove it to see if that would at least fix the problem but it only seemed to get worse. So I waited until I got off work to change the motor oil back to 5w-30. That didn’t seem to help much either. The next couple of days the idling was getting pretty worse to the point of stalling every time I came to a complete stop, and when I accelerated it would sound what seem to be backfire coming from the muffler.
This past Friday, I went to visit my buddy so he could check to see what was going on with my car, he had a diagnostic tester so we plugged it in and we got the code P-0302 “Cylinder misfire”, so we decided do a wet/dry engine compression test and while we were at it we also inspected the condition of each spark plug. Each spark plug looked good, there was good compression all around and the fuel pressure looked good. We checked the codes to see if anything would pop up but we didn’t get anything on the diagnostic tester, but when it came to starting up the car after the test was finished, it wouldn’t turn over. Now the car has a hard time keeping the RPMs above 0 without it stalling.
The next day I drove my Civic (which was stalling at nearly every light and stop sign) to a nearby tire and battery shop so that I could use their diagnostic tester to see what exactly was going on in my car. We still got misfire codes but now for cylinders 1, 3 and 4. I guess since driving my car in this condition I was running on basically one cylinder, so we decided to recheck the sparkplugs and to our discovery the tips were blackened, the distributor cap and rotor had real bad corrosion and we barely put those in this past February, the spark plug wires looked new but we weren't taking any chances, so we just went ahead and bought new spark plugs, spark plug wires and a new distributor cap and rotor. But still with everything installed there really was no difference at all and we still got misfire codes.
Next we pulled the spark plugs wires from cylinder 1 and 2 but had no effect on the rough idle and we also pulled off the fuel injector connectors while idling on cylinder 1 and 2 but those still had no effect on the rough idle.
So far, my buddy and I are stumped as of this moment as to what is wrong with my car, I apologize for the long story, but I’m trying to remember every detail out there so that it could be clear for those of you reading this, so what do you folks out there think the problem might be?
Thank you.
