hello everyone, looking for some ideas, took out some standard plugs and popped in the platinums, now w/ boost it stumbles, pings surges, you name it, ran fine with the regular plugs, make sense to any one or am i crazy?
thanks for helping guys, everything is sealed up, as for the plugs they were pre-gapped and i was under the impression that you should not mess w/ the gap on platinum plugs i pulled 3 of the 6 and they look good. i just got back from a drve here are the exact symptoms
cold start ok
hot start takes about 15 secs to fire
drives ok with no boost
the more boost the worse it gets
wot total bog down
maybe spark blow out, anyone think it may be fuel, dirty mass air sensor???
