Sartz, the only thing that is left from my standpoint is for you to do a compression check. I suspect that you may have a bent valve or some carbon buildup beneath the intake valve. How about the ignition module?I have run out of options from this end, Ken
Starz, sorry but I posted this in the wrong thread, however, if you can give me a complete discription I will be glad to offer some of my expert and sometimes down right dangerous advice, Ken
Sratz, This is nothing to worry about.While on deceleration raw gas is not burned and will ignight from the hot gas passing thru the the engine.I suspect that you are going down some steep grades.Sort of like watching a NASCAR race and seeing the exhaust pipe emit a bit of flame. Nothing to be concerned about.
