Hi,
started to get ready for a compression test last night, pulled my plugs and heres what i saw:

- slight amber tone on ceramic end (about 5mm above thread area)
- tip in good shape (using recomended NGK platnums)
- slightly white coating on gap-metal-thingy (thats a technical term)
- black carbon deposits (thin) on combustion side base w/ just viisible metal flakes

i took a polaroid of em, but the quality was so low it wasnt worth scanning. from what i know about plug reading the metal flakes, amber on ceramic and white coating mean that im running too lean, but to then have carbon deposits too....?
this is in an h22a4 with int/exh/pullies (not that they matter in all this) AND V-AFC. Also of note, i peeked at my pistons and they looked like carbon-cakes, only time ive seen other pistons is outside of engines and in photos... is that a normal condition?

Ive now got the V-AFC set to -8 at 6500rpm wot, highCam (everything else is in the -2 to -6 range). i reccently took it to yoshio's in toronto (bad experience, i wouldnt recomend him) for a (not calibrated dynopack) run, he, using a wideband O2 had it set to somthing like -14... ive since mellowed it out. vtec-in is at 4600 too.

Any of you mechExperts have some advice? Am i still running too lean, ok? the car feals good these days, and of course i use 93-94oct gas all the time.

TIA

oh yeah, couldnt do ocmpression test because gauge was too short and narow, barowed it from my father-in-law, i geuss Fords dont have similar head, plug-well dimensions...
