Re: 4.7l misses at start up
is it actually misfiring, or just idles rough, do you have a check engine lamp on? The 4.7l is known to have a bit of a rough idle at times, mine comes and goes. Never get a check engine lamp, last I checked I was not even getting any misfire counts on any cylinders and I haven't cared enough to recheck since then.
