Yup,educated me too,been a while also,can't explain my post,cause I didn't see the drac,I assumed it was not on 2 wd ,found more good info on udmodule.com
That's where I always mess up,returnless fuel system,no egr, return system,yes,g.m. always emptying the parts bin, before a change,got to keep on your toes with this stuff,I'm still thinking about getting a horse,lol
Well,not the first time I'm wrong,so focus on left bank,per code,test intake gasket with water in spray bottle,rpm change? during test?,not a perfect test either,can't get at underside ,other, swap 02sensors,side to side,see if code follows?
Yep,no spray foam,open cell,sponge,so,as I watch my truck rust,all new riding mowers have a water port for cleaning the deck,would that be something to think about,hole drilled in spot on inner wheel well,hook up hose?
Vent valve is open when vehicle is off,purge valve is closed when off,a guy did a test somewhere on here a ways back,purge valve opens on decel,he hooked up a test light to watch,now he didn't test light the vent valve,so during evap leak test,purge opens,vent closes for small leak test,then opens for large leak test?
