Ok, I would like some thoughts here. I have a double cab 2004 3.4 with s/c, 90k, URD's fuel mods (injectors, fuel pump, thermostat, plugs and 2 piggy back computers). It is tuned to a t and has run perfectly since 2006 until I did a rebuild last year (suspension) and it sat for about 6 months. I got it back on the road and have had this random stalling issue for a few months. I get dtc 0101 and 0102 codes. It will stall with absolutely no warning and sometimes hard to re-start. It takes 4-5 tries then fires back up like nothing happened and runs fine sometimes for 15 minutes, sometimes a few days. I have put in 2 new mafs, did plugs and wires (had a misfire code). Fuel pressure is good, stock intake, good battery, all vacuum lines are intact, grounds are good and the electrical is all stock ie no aftermarket alarm. I have had my wideband hooked up and watching it and noticed that it will get real rich right before the stall. I am in the process of hooking up my obd software so I can data log as well. I have searched for the past few days with no solid answers. Thanks for any ideas in advance!
