Guys cant figure out what the hick up / slight bog is. I was thinking may be its mis-fire but i dont see my EGT Temp spiking. Just checked my MPG & only got 13.1per gallon but i think this is normal? Before my 3.00 pulley & new plugs i was getting high 14 & 15mpg.
Well its so easy to get power now so im thinking the pulley is not helping me out on the MPG.
O.K. Checked the color of the plugs & its getting to the Tan color / Gray color.
But...yes but. Some plugs are at the tan stage still & while other have already hit the gray side.
Oh with the THUD part of it. I just tried changing the gap. From .037" to a .040". Still a slight THUD but not a long duration of a thud. So not a hick up / bog feeling.
Although i can still hear the THUD just a tab bit in the higher RPM range but still driving very slowly.
Maybe my car just doesnt like the smaller gap size?
