and it's honestly one of the easiest things I have ever done. I kinda "***** foot" my way around my truck making sure I don't break anything so I was hesitant to do this at first. I used the search, hey how about that, and found this thread ( http://www.ranger-forums.com/forum2/...ad.php?t=36066
)and made sure I knew what I was doing.
I decided to start my truck, after the engine was warm of course, and pull the brake booster hose off and put my thumb there to keep a steady idle. I poured in a little less than a 1/3rd (later realizing I should have done more) and put the rest into my gas tank. I waited a good 20 minutes and started the truck back up and got little to no smoke at first. After a brief drive around my neighborhood I had more of a noticeable "cloud" behind me but I think if I would have added more into the intake I would have seen more smoke.
Overall I'm glad I did it and I am recommending it to most of my friends, as some of them have trucks with 150k+ miles so I hope to see more dramatic results with them. I notice smoother revving throughout the power band and am waiting to fill up on 87 instead of 89 to see if it has curred a previous sneaking ping here and there in summer days.
