Thank you so much for this thread and I'll see if you guys can help put my mind at ease.
Ten months ago I was driving on the freeway and the car shuttered, it felt like a pulsating throttle so the car would lurch forward then slow down and repeat a few more times then came to a stop with the engine killed. The fuel pump was sporadic when turning the key and eventually you couldn't hear it turn on at all. This was the 2nd time I ran out of gas because I wasn't paying attention and I know that will kill the pump pretty quickly. I left the next day for a 10 month deployment and the only thing I had time to do was put fuel stabilizer in it and the oil was changed the day prior.
Fast forward to today. I followed this guide and the car started up, however you can tell it was running rough. It pumped out quite a bit of white smoke as I let it warm up. I took it for a drive around the block in first gear 3k rpm to be as gentle as I can. I felt the slightest undulations in power, that lurching sensation again and the check engine light was on the whole time. So I'm curious if you guys have had anything similar happen after 10 months with stabilizer in the tank? White smoke can also be valve seals, but I'm not sure if this is a common problem with S&S. I'm going to take it on a few more drives to see how it reacts, but I'll take any info you've got.
You need new fuel. Check out this test, you’ll be surprised:
You can jack up the rear so the fuel collects closer to the fuel pump outlet, or jack up the front, if you prefer to undo the sender unit. It is easier to use the fuel pump hole.
