Ok i have been working on my friends car and getting it to idle and run better but this is my first camed car and i get get the idel down right for some reason. When it first starts up it wants to surge a little bit and every once in a while usally after about 15 minutes of driving and then 15 minutes of letting it sit it will die on us. He has a patriot 226/226 duration .585 lift cam. Any guesses as to what might solve would be helpful here are the tables i have edited and the values that are there now.

Try leaning out your VE table at 400, 800, and 1200 rpm.

Start with 10% lean (multiply values by .9) and keep going from there.

Yeah what Redhard said

A lot of hard work and effort went into his write ups as well as several others on the board and it is very very much appreciated. I'd be lost without your help. Thanks guys!
