I have a 93 civic ex with the D16Z6. It seems to have a fuel delivery issue. It sometimes starts rough and when it gets running it will be running fine and then all of a sudden almost dies. If I get in the gas pedal it will clear out for a minute but then comes back. It felt like the fuel filter was clogged so I changed it and still nothing. It will stall out occasionally and then it's hard to start back up. Then it will run good for a minute and then bog out again. Help please?

 

Is it only when it is idling? If so just clean your idle control valve and see if that helps.

 

Not only when I'm idling it also does it when I'm driving. It will just bog out and then it clears out and goes again

 

When was the last time the plugs were changed? Here is what I would do:

Clean IACV-If that doesn't work...
Make sure you have good airflow IE: change filter and check if anything is clogging the airflow-If that doesn't work...
New plugs, wires, cap and rotor

 

I don't know what the IACV is but I can tell you I just changed the plugs, and wires about a month ago and I'm running a K&N cold air intake that was just recharged.

 

how many miles??
iacv is idle air control valve (also called eacv for electronic air control valve). should show a CEL for that (i think)
if it started right after the wires were changed, then you may not one on good enough or you put a wire on the wrong plug. (guess all the plugs are on tight)??
Is the timing right?

also wanted to ask: is that throttle body or port ???

 

It's a throttle body with 183k miles. Also it ran great for about a month on the new plugs and wires.

 

is that the original distributor - or when was the distributor changed ??

 

distributor assembly was replaced at 160,000

 

i would do as INJEN suggested and put on a new cap and rotor
