Hello again my friends, 
long time no see i know, lol. Well my first problem with my ls. I was driving back from south dakota and was passing somebody on the highway when all of a sudden i get a engine light blinking, at first it was blinking but by the time i had stopped somewhere and turned the car off it was constant. I could definately feel there wasn't a cylinder firing or something (rough idle) and man did it struggle going up a pretty steep hill. Well i took it to the shop and code showed up misfire cylinder 3. Ok no biggy, change the coil, right. Well then he suggests i should go ahead and replace the boots because they noticed quite a bit of oil on the plugs when they pulled them out. They first thought it was the car trying to compensate for the misfire,so i said go ahead and replace all the boots and then i figured i better change the valve cover gasket also. Ok they get it alll back together, and i said i would pick it up that afternoon, and he said he would test drive one more time before i picked it up, he had driven 8 miles to make sure everything was ok.. Well I get there and the car hood is open once again, and i guess he said his second test show cylinder 3 misfiring. Is it likely that just two coils went out or going out at the same time. I have talked to him recently so i am not sure where he is at now. Just getting nervous if it may be something else is all.
