[truckin 79]

Well it finally passed the smog test what a relief. The good thing is I do not have to run emissions test again unless I sell truck. I can get a collectors plate on it and just renew every 5 years. Now I can spend more money on truck to fix the things it really needs like front shocks, rubber brake lines, fix emergency brake, tint the front windows, swap out a broken leaf in the back, take out dual tank hoses, change drivers fender and maybe add air conditioning.............oh and paint it of course.
I am with your jpmerf, it makes no sense to add exhaust gases back into intake. I guess it makes sense if you are already running really lean and it cools off cylinder and burns gas again. If vehicle is already running rich then it is just adding even more rich fuel in cylinder and then cooling it off. Thanks for all your help everyone and jpmerf
