Did some searching, but nothing 100% fits my problem. It only does it intermittantly. Car is an 02 3.8L LS. On a hot start everyonce and a while it will start super rough. Then if I shut off, and turn it back on everything is fine. I can also watch the tack jump 400 rpms up and down. It has done this since I bought it at 33000, dealer couldn't find it or recreate the problem. Its got 103K on it now. My gas mileage is ok, not as good as it used to be, I do all highway and put on about 300 a week, and spark plugs and wires are good, just changed the fuel filter, cleaned the MAF, air filter ect. When it was at the dealer under warrenty they did a pcm flash upgrade on it. I was thinking it could be a fpr, or an iac, but everytime i throw on the dirty clothes to look at it, the problem doesn't exist. OH yeah and it used to do it only only like 2-4 times a year, now its getting worse, it has done it like 4 times in the past month. Any sugguestions, and am I looking in the right area
