Change fuel filter , put in 5 gallons known good fuel , see what happens . You won't be out anything . Filters need changing , need fuel to run . Don't fill it up , in case tank has to be pulled to install pump .If that is the problem .

Cant really tell the color. Seems like white smoke. Litle bit of water dripping from pipe. Outside temp is about 45. not really a smell just regular exhaust smell. I did notice that if its in park it will not sputter much. But if i put it into reverse or drive, itll sputter more and act like the engibe wants to die

If you haven't had your plugs changed since new, it would be a good idea to do so. I'm assuming you have some miles on them since you mentioned it's out of warranty. Replace your rubber boots as well as they do wear out.
This may fix your misfire. Replacing spark plugs is routine maintenance anyway.

Got coils 5&6 and spark plugs. Runs better. Did notice that when it acceleratea itll shake for like a second. Then catch itself and run smooth. Called the mechanic back and he said thats sign if the other coils going out.

Did you have him change all 8 plugs or just those 2? If all of them, did he replace all the rubber boots as well?
If he did all the boots, you can get another coil and swap one by one of the remaining 6 to see which one is about to go. If after you swapped one and still does the same thing, then that one you pulled was still ok. Put that old one back on and put the new one on the next old coil until it improves. Then you'll have the culprit.
Good luck
