Ok I'm running a 2000 Civic HX manual with about 187000 miles. It has had good routine maintenance and I just had the belts/water pump change at 180ish.

For the last couple weeks I had been having a problem when cruising at a steady 2500 RPM in 3rd gear I could feel a miss and the CEL would flash for a few seconds. As soon as I accelerated it would go away. It does not seem to occur when driving at faster speeds in the same RPM range.

I have used HEET and injector cleaner but the symptoms have not improved. I installed new plugs and wires about 12000 miles ago.

I used the jumper trick and counted the flashes on the CEL.

I think I have the correct translations.

12 - EGR - exhaust gas recirculation lift valve
71 - random misfire cylinder 1
72 - random misfire cylinder 2
73 - random misfire cylinder 3
74 - random misfire cylinder 4
80 - EGR Valve/Line

I guess the question is - Can the EGR cause the misfires? The car doesn't seem to have degraded mileage but I don't want to destroy it.

I found a Duralast EGR for pretty cheap and it looks like an easy install.

Here is what I found http://www.tegger.com/hondafaq/egr-fix/index.html

Any help would be appreciated I am a little over my head on this one....




Oh yeah, great forum!
