Have the puter scanned, sometimes the O2 sensor could cause that kind of BS too.....a scanner with datastream display like the one I own could show something like that.....

AH, I see. O.K. Well without actually experiencing this problem I'd say you're describing something electrical, not fuel related. Best bet is to take it to a shop instead of guessing and spending in the wrong place.

Your best bet is to PM Nutbar or give Jeep thrills a call
