Alright, now my car was running real nice at one time (1 week ago)....idle/cruse was a 14.7 A/F or there about, and at WOT it was pretty much bang on at 12 A/F.

Now this was when I was running Sunoco 94, now given gas prices I switched it up and started using Shell VPower 91, now I'm noticing that at idle/cruse it still seems to be 14.7 but at WOT it starts off at 12 A/F and then near the top of the gear drops off the charts (below 11 A/F)....


Now when I was running Sunoco 94 I was finding my A/F lean so I got Randy to add fuel. With 94 it was running 13's and then randy brought me down to 12's and now with 91 i'm running 11's.

I guess what i'm asking is would the 94 be causing it to run leaner than the 91, or would the 91 simply not be burning well and showing a rich condition?????

Has this happened to anybody on here? (limited FI base here but maybe its something weird with our cars...???)
