Now when I'm on the highway in 5th gear (3.31 rear) and give it about 1/3 throttle I get a real bad miss. I re-checked the connections on the COPs and the injectors (unplugged them to give me some less clutter to work around). Is there anything else I should check? I put quite a bit of anti-seize on the plugs when I put them back in, but made sure there was none on the tip. Also, i used PB blaster to spray down in the plug recesses when I was trying to break them loose and when they did come out it leaked down in the cylinder, it smoked pretty bad when I first started it but stopped quickly. Any ideas let me know what y'all think.
