I have a 93 Nissan Sentra. The engine is running rough.The compression is fine.The wires and ignition are okay.But numbers 1 and 3 cylinders are not working.When i pulled the numbers 1 and 3 cylinder- spark plug wires,it does not respond.

 

It is amazing what a set of new plugs could do..

 

If 2/4 cylinders work then your distributor is okay.
You need:
New cap/rotor
and new plug wires
and new spark plugs.

If it still happens after that you have 2 dead fuel injectors.

 

Ya I have the same problem with only cylinder 4, I found out today it was the fuel injector. You might want to check the injectors before you buy anything.

 

Is there a good set of spark plugs and plug cables anyone would recommend?

 

can u all help me who know the timing mark of this enjin GA16
