Hey Bud...tried the Berryman B-12 injector cleaner but no change...I am convinced it is electrical...computer or whatever when it gets hot is breaking down and causing the spitting coughing at low R.P.M. because when I drop down a gear, increasing the R.P.M's it performs as it should...not sure if a local mechanic will have the diagnostic tools to figure this one out and as much as I hate the thought, I think back to the dealer is my best bet...won't be cheap but hopefully they will find the answer...just wanted to thank you for at least "jumping in" to try and help (you were the only one!) Thanx again!
