I have a 96 accord ex auto w/ a V6 (original engine). I recently had my vehicle inspected and received misfire codes for cylinders 2, 5, & 3. I replaced all the spark plugs, the dist cap, and ignition control module. This solved the problem. The car has been garage kept and only started (and let idle) a few times for a few months. Well, I take the car out yesterday and the check engine light is on, so I have it scanned and the fault code is cylinder 5 misfire. I pulled the spark plus yesterday and it looks okay. Can anyone lead me in the right direction?????????? Thanks for any help in advance

Check the resistance of the plug wire, look for any damage. Just because it's new doesnt mean its good.

If the misfire code only pops up when you are cruising at part throttle, and the car has 100K miles it may be that the EGR ports are partially clogged.
Remove the center lid/plate from the top of the intake manifold. That is the EGR manifold. Check it is clear of soot and carbon build up. Clean with a vacuum, flat head screwdrivers and picks. Make sure the ports to each runner is clear. Reseal EGR chamber plate. Go for a drive.

It's been less than 24hrs, we all have our own jobs/projects.


EDIT:
Remove part #5/6 to clean the troughs on top of the intake manifold.

 

u can always Google it
