How do you fix a slight knocking noise in engine..?

Question:
automatic fuel injected civic 92 model...of lately i'm hearing a slight knocking sound in the engine .....what can be causing this...? apart from that i'm still faced with the trimbling problem with the engine during cruising speed.....i checked the spark plug pulling one by one plug wire out while the car is idling(On/running) doing that cost me alot....after pulling out one of the plug wire & putting it back the car started idling slow like it's about to cut off.... i decided to switch off & restart...well the car keeps tumbling & for nothing it wanted to start....by luck i had a friend with a vehicle like my own so we took out the distributor from HIS car & tried it....MY car started.....can anyone explain what cause the distributor to spoil in MY car...?

Car would not start...?

HHMMMM Actually it sounds like you have a Valve sticking. Pull off the valve cover, remove spark plug wires so the car will not start and have your buddy crank the engine while you look at the valvetrain. Check to make sure that every valve is going up and down smoothly. the slight knocking you are hearing might be the piston slightly "tapping" the valve shut because it stuck open just enough to get tapped. This would also cause your cylinder not to fire properly. Which would make the engine run rough and have a rumbly feeling to it and if the timing was just so that your car was relying on this cylinder to get the engine started it wouldn't do it but changing the distributor gave the valve time to close or all the wiggling jiggling let the valve close, either way it would start again and appear that the dist was somehow the problem.

Try using a more higher octane fuel like plus or premium. If that fails then you got a loose valve.

did putting the other distributor in take away the knocking? Is it more like a knocking, or a ticking? Ticking could mean that you need to use a higher octane gas. Or you might need to get the engine treatment to clean your lifters Spark plugs are relatively cheap. and if you aren't real sure, start with the least expensive thing.
