Happy New Year!!!!! I have 94 accord that has developed a miss at idle. It seems to drop and catch itself before it can die. It doesn't seem to matter if i'm in neutral, drive or park. I'd like to get ahead of this before it leaves the wife stuck somewhere.

Thanks,

Bone

 

Happy New Years back to you..Help is on the way with an answer..
All you have to do is wait till everyone gets on the Internet and back to the forums..

Welcome

 

Bumps head, wakes up, changes trans fluid in the Pilot, sway bar end links on the 5th gen, checks fluids and tire pressure in all of the others...oh, back to work

Start simple. Are the tune up items (cap, rotor, plugs, check wires, ect) up to date? Does this only happen once the engine is to temp or when warming up as well. Any stored codes (CEL on or came on while driving)?

 

all of the components are a couple months old. I no for sure it does it when I get up to temp it may also do it on it's way up to temp.

 

Usually a miss is ignition related.

Suggest loosening all spark plug leads (just sitting on spark plugs) and sequentially removing/installing spark plug leads. Missing cylinder will be indicated by no change when spark plug lead is removed. Bad plug, damaged boot, wire, or cracked distributor tower are possibilities.

It's also possible, but less likely, that miss is result of improper air/fuel mix. This would result from a large air leak on intake manifold or EGR malfunction (EGR valve open at idle).

A faulty or fouled injector (very rare) might cause a miss. This would be isolated to one injector by spark removal check above. Missing cylinder again would show no change when spark plug lead is removed. However, in this case the reason would be a damaged injector.

good luck

 

You might want to clean the EGR ports on the intake manifold. That can cause the car to stumble at certain rpm.
