went out tonight and checked for leak at MAF,had a clamp a little loose,tightened up clamp P0174 code gone but now have P0300 code active,after engine runs about 60-90 seconds,engine idles good until code pops up,then starts running rough.10PCM-P0300 is a misfire code,makes no sense that it idles good and then rough after a short time,you thick that it would be rough from the get-go.

sounds like you're having a harder time with your header install then I did!
Double check that all of your plugs are tight and none are cracked. Double check that you didn't break any of the plug wires. Double check that all the wires 'clicked' on the plug and you got two (2) 'clicks' when you put the wires on the coil. Double check that have at least 3 beers when you're done.

yea, I'am having a few more problems that I planed on.Worked on heavy equipment for 35 years,and my own auto's that long. Wished I would have had LG installed headers.This has been one big project for sure! I do appreciate all of the help from everyone. Thanks
