Here are the photos. cyl 2 looks great, as well as cyl 3. Cyl 4 was a brand new plug(previous fouled plug was installed in cyl 6)Hmmm. Looking at the display, it shows 2590 misfires for #2 cylinder, but -0- for the #4 cylinder?
But back in reply #17, the #2 plug looked OK, but the #4 has the signs of oiling on it?
I would be interested to see the difference in 3 spark plugs at this time:
* #2
* #4
* known good control spark plug (ie: cylinder that never misfires)
Valves were installed with new seals by the shop that got me the new heads. They have under 1000 miles or close to it.Stuck valves? Dirty injectors? Have you cleaned your maf sensor ?
Egr, i don’t believe so, no. That wouldn’t cause misfire on a single cyl…? Would it?Did you clean the egr? Is the cats plugged up?
Porcelain is good on said SPs. Just checked.One other point I haven't seen mentioned, check the porcelain on the plugs for cracks. I'm not saying I've done it, or haven't done it, but cracked porcelain can induce a misfire as well.
Cleaning egr atm, upon taking it out, i remembered i did clean it when I did the headsDid you clean the egr? Is the cats plugged up?
