terryb Report post Posted January 19, 2013 I think your car is taking autonomous trips in the night and resetting its figures.Looks like a whole lot more than 1300 miles to me. Quote Share this post Link to post Share on other sites
acdii Report post Posted January 19, 2013 They were replaced around 4500 miles, car now has 5800 miles. It was easier than I thought to get them out, two small bolts for the aircleaner/cover, loosen the band on the throttle body, two more bolts for the snorkel and pop the whole thing off, but dont yank it as there is an electrical fitting taped to it, and has to be unscrewed to get it completely off, but I was able to get it up and away enough to reach the first 2 plugs. one bolt for the COP, then I can get the plug out.

lolder Report post Posted January 20, 2013 I think the black edge of the plug looks like too rich a mixture. Quote Share this post Link to post Share on other sites
wmpwi Report post Posted January 20, 2013 What's the recommended plug replacement schedule? The pictures don't suggest 5K if that's only 1.3K :headscratch: Quote Share this post Link to post Share on other sites
terryb Report post Posted January 20, 2013 Normal replacement is at 100k. Quote Share this post Link to post Share on other sites
acdii Report post Posted January 20, 2013 Normal replacement is at 100k.^that! I forgot to subtract EV mode so that is only about 900 miles. Quote Share this post Link to post Share on other sites
wmpwi Report post Posted January 20, 2013 OK, so has anyone given you any clue as to why you're plug (as pictued) looks like it's all but gone? I've been screwing around cars all my life and I've never seen anything dong that short of an acid bath. :fear: ^that! I forgot to subtract EV mode so that is only about 900 miles.

acdii Report post Posted January 21, 2013 The center electrode is OK, its very thin out of the box. The SOOT however is not normal, and Ford has no clue, well, they would if they got off their collective asses and actually took the car and analyzed it. It needs to be put on a dyno with an emissions probe, cylinder compression probes, fuel metering, O2 metering, and run it at 65 and find out why it is using so much fuel.

wmpwi Report post Posted January 21, 2013 Ahhh, the 'fine wire' spark plug. You must be buring rocket fuel. That would explain it. Quote Share this post Link to post Share on other sites
acdii Report post Posted January 21, 2013 Just for kicks I should pull the plug out of my utility tractor with 80 hours on it and compare. Quote Share this post Link to post Share on other sites
acdii Report post Posted January 21, 2013 Since its so freaking cold out, decided to pull the plug on my little 20CC gas engine that the last flight on was into the ground, so the plug is a bit wet from oil still since I have killed the ignition before it hit and windmilled fuel/oil without spark on its way into the ground(wing snapped off in flight). It was tuned on the rich side since it only has 1 1/2 gallons through it, and still being broken in. Notice no carbon build up. It also was run cold with no cowl, so never really got hot. It has a 14 ounce tank good for 30 minutes run time wide open, so it has about 6 1/2 hours run time on it. Quote Share this post Link to post Share on other sites
