Well i put sea foam throu vac line and put bout half in tank , im gonna do it again thru vac line since it has already improved quite a bit. When engine is cold is still sputters really bad but when engine is fully warmed up it run s almost completely normal again. Also the bottom vac line on egr valve , had a big crack in it (almost broke in half) so fixed that and the nipple that vac lin goes on was completely pluged shut from carbon buildup so took care of that also and check engine lit is off now . What is causin it to sputter so bad when its cold?
