Ok i poped some HEET in that sucker with some premium for the hell of it. Still waiting for it to get better although its random at how bad it is, Sometimes its doing the buble thing quite a bit and very shakey sometimes not. I have only ran about an 1/8th of a tank so maybe i should just give a little more time. About how much of this tank will i run before i see results ? could it take up to 2 tanks / 2 treatments ??
