I have a 1994 Honda Accord LX which isidling/running rough

It was running just fine then the symptoms started.

I have checked and have the following:

Timing is correct
Compression on all 4 cylinders
Spark to all four cylinders
Checked wire, distributor cap and rotor and are all OK.
Spark plugs are gapped correctly but appear all carbon soot.
All the fuel injectors appear to be firing.

With the car running I can pull wires from cylinder 1 and 4 and there is no change im performance. When each wire from cylinder 3 & 4 are pulled are will stall out.

No check engine light on and no codes are stored .


Any help would be greatly appreciated.

 

check your altenator that could be it get new wires and spark plugs it may runfine but there is a flaw try that!
