2004 Suburban, P0106, P0171, P0175
2004 Suburban, 5.3, Truck Norris cam, long pipe headers, no cats. This is a recent build and I renewed every possible part I came around. All new sensors, pistons, rods, etc. Used the old coils and injectors, but the injectors were cleaned. (hopefully done correctly) am at my wits end. I replaced the MAP sensor, making the P0106 go away - for about 3 hours. I cannot figure out why bank 1 is lean and bank 2 is rich.
I replaced both oxygen sensors (only the front ones are left), changed the MAF with another one I had laying around, new MAP sensor. I am trying to get it to run well enough to get to my tuner.
I have cleared DTCs after every change and made notes. It all started with a misfire from a bad plug wire about a week ago and has progressed into a world of monkey crap. It idles OK, but around 900 rpm. No power upon acceleration. no backfire. no guts.
Can ya help a poor old man out?
