OK, just pulled all my plugs, cleaned and re-gapped them. (some reason they were all gapped about .045in when manual calls for .031 ??, damn service shops). Gonna see if that makes any difference. The colder it gets, the worse the problem seems to be, although even when fully warmed up, still choppy acceleration. Really starting to drive me nuts. Gotta pass AirCare in the next week or so too. <img src="/forums/images/graemlins/frown.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />
