I've always been setting the Sparkplug gap on my car at .035. Since thats what is listed in every book that I've seen, and also because of the TSB. But I noticed the sticker under the hood of mine, and it states to set the gap at .050. So just for the hell of it I changed the plug gap from .035 to .050. I've notice that the idle is better, so is throttle response. Also computer shows that the MPG has jumped by 2 MPG in town,. I haven't had the time to take her out on the highway yet to check highway MPG. I think, because of that sticker, that the car was built before the TSB was issued. My question is, when they issued that TSB, did they also have to re-flash the PCM, so that you could set the plugs at .035 for cold weather starts ? If so, that maybe why my car runs better with the plugs set at .050. If they didn't need to re-flash the PCM, then why is she running better with the gap set .050 ?
