Thanks for the reply. It was not missing this bad before the swap but yes when I laid into the gass it would usually backfire and miss along with massive power loss. It would almost feel like it was starving for fuel type of feeling. Now if i step on it either from a stop or in any gear it misses and not responding like a V8 should at all. I will have to try the propane thing but I have sprayed carb cleaner with it running all over and didnt see any leaks when I did that.
