Weird???
Hey guys, Ive been trying to think about how to explain this but its hard to do. So here goes nothing. When im at a stop sign, the truck will be idling good, but the engine will change its pitch to a deep grown. Tac doesnt move and everything seams great. Just weird. Like a deep sound you hear way down in your ears. Its also Irratic. It did it before i took it apart but im just wondering whats causing this? I drove it to college today, bout an 40 miles so 80 miles round trip, city and highway mix, i went through a tad over an eight a tank. Runs really smooth since i put the new cap and rotor on. No more little jolts and an idle. Sometimes i think it stalled it runs so smooth lol.

Quite Possible, Its definatly running smooth, i acually got better MPG than my fathers diesel on the highway, I know put a trailer behind them and see who gets the most then lol but im happy. Went from probably going to cost me 25 dollars a day for gas, to 10. Dad and i sat down and figured it out
