Hey first time posting. I picked up a 2001 GMC Savana for a camping/motorcycle hauler. I'm not exactly sure if it falls under the gmt-400 nomenclature but it does have a 5.7 350 with L31 code.
It has a miss and and an engine code related to the csfi injector setup that seems to be problematic in these particular engines
So I'm trying to figure out order of operations for how I'm going to attack the repairs
I loaned out my CC to rock auto for a hour or so and ordered the GM upgraded spider assembly, new plugs, wires, cap, rotor, fuel filter and a set of felpro upper intake manifold gaskets
The drivers side catalyst has fouled and the matrix is loose inside so it needs to be replaced, I'm not sure weather to replace the catted Y pipe or to go with an offroad Y pipe and delete the rear 02s in the tune. I'm not looking to make her fast just reliable
Same with adding an efan setup, the gains and reduced parasitic drag seem great but the mechanical fan is simple stupid and I like that I can audibly hear it working.
So I'm looking to talk to other guys who have vans similar anyone have an offroad Y pipe ? If so what brand ?
Thanks
