Help,,opinions, ideas??
 

Well, here are two pics of my sparkplugs. The clean one is from the drivers side and the dark one is from the pass side. Didn't need to do all eight since these two represent what each side looks like. Funny how the drivers side look good and the O2 sensor that is in the exhaust is the one that was on the car when I bought it. The pass side has a new O2 sensor and is physically different that the one in the drivers side. Hmmmmm. Deductive reasoning tells me that could be a problem.

Im having a problem w/the car bucking and surging and there is NO POWER until 4k RPM! Cam was installed right, timing is a little advanced, fuel pressure is right, MAF is clean. What gives????? Herman, I give up, I have to see what you can do for me.
