    P0101 and P0106 Codes

    Yes, just unplugged it for now while I have a new one being shipped. The CEL is on, but it was almost to the point of being un-drivable due to running so rich and misfiring. The plug is super easy to get to, right on the passenger side frame rail.

    P0101 and P0106 Codes

    Figured I’d update this in case anyone is experiencing the same things. Turns out it is the o2 sensor, Bank 2 Sensor 1. Finally tried unplugging it and sure enough, the truck runs great now. Was getting 7.2 mpg, now averaging 16.3 which is by far the best mileage I’ve seen with this truck.

    P0101 and P0106 Codes

    Seems a little better but definitely still running rich. What other sensors, besides the MAP and MAF, communicate with the PCM to control the fuel trim? The truck runs normally at a cold start, but once it warms up a bit after 20-30 seconds or so and comes down to 500rpm it'll start stumbling.

    P0101 and P0106 Codes

    Also, this all started shortly after the oil was changed at a shop, where they overfilled it by around 1 qt. Any issues/things to check that could be a direct cause of this that might narrow down my search?

    P0101 and P0106 Codes

    I replaced the intake manifold gasket a few months ago. I'll pull the throttle body and will take a look.

    P0101 and P0106 Codes

    Hello, My Yukon is idling terribly and seems to be running very rich, has black smoke out of the tailpipe and is getting awful fuel mileage. Used a scanner and it is throwing P0101 (MAF) and P0106 (MAP) codes along with a random misfire code, which I figure is related to the 2 previous codes. I...

    Sending Unit Repair Costs

    Filled up my new to me 2003 Yukon yesterday. Smelt fuel and sure enough have some leaking out of the top of the tank somewhere. Im guessing that since the gas gauge is not working the sending unit needs to be replaced anyway and might have corrosion issues causing the leak. How much should this...

    2003 Yukon XL Non XM AUX Input

    Would there be wires from the cassette deck that I could tap an aux input into? Similar to the XM aux mod with 2 wires and a ground? Rather not dump bunch of money into a touch screen system, might look into an simple aftermarket deck.

    2003 Yukon XL Non XM AUX Input

    I had an 02 yukon with the premium sound system, no bose or xm, and used something similar to this with 2 RCA ports that I could plug in a RCA to AUX cable and it worked well...

    2003 Yukon XL Non XM AUX Input

    picked up an 03 Yukon XL. Has the Bose speakers but not the XM radio so I can't do the known XM aux input. What do I need to get an aux cable for the stock radio? Prefer one that doesn't mess with radio frequencies, rather have it hard wired in. Thanks

    03-06 Suburban Rear Captain/Bucket Seat Question

    So they fold down so the backs are level with the rear cargo area? What about the space in the middle between the seats?

    03-06 Suburban Rear Captain/Bucket Seat Question

    Looking at purchasing a 03-06 Z71 Suburban and a few I have come across have the 2nd row captains chairs. In my tahoe and previous yukon I have had the rear bench seat that, when folded down, creates a flat floor. Do the captains chairs do the same? Or are they folded in a different manner? Thanks

    po300 code, interesting possible explanation?

    While driving at around 9000ft on the highway in CO my car started going into limp mode and the check engine light came on. I would pull over, wait 2 min or so, start back up and everything would be fine for 2 miles or so and would repeat. Once I got to the exit I let it sit for 25 min. or so...

    astEngine Tick When Passing Cars/Walls?

    I've got a 2004 tahoe, 5.3 motor. 195K miles, runs great. When driving through a drive thru or past parked cars, theres a noticeable ticking noise. Not super loud, but still noticeable. When I am stopped and rev the engine or have the hood open and rev it, no ticking or abnormal noise. Anyone...

    Windshied Washer Fluid Disappeared??

    Reservoir and pump are good, a hose that runs along the base of the windshield under a plastic cover is leaking towards the passenger side and emitting fluid into the passenger side engine bay. Unfortunately the plastic piece is held on by a bunch of fragile plastic clips so I am waiting for a...

    4l60e planetary gear replacement

    I'm going to nurse it along until I can find a good, reputable shop in the area that will do the work. Of course the one time I've had anything go bad with these trucks, it's in a super inconvenient time and situation...

    4l60e planetary gear replacement

    Will a transmission shop do the 4l80e conversion with a warranty? Just left where all my tools and garage are for 5 months for school, and this just started happening right after so I can't work on it myself which is incredibly annoying. Any idea how much labor would run me for a shop just to...

    4l60e planetary gear replacement

    My 4l60e is starting to whine in 1st, and sounds like a turbo de-spooling when shifting to 2nd. From what I have read this is due to a worn planetary gear. Does this require the entire trans to be dropped? What is the estimated cost to replace? Drives and shifts fine other than the whine, whine...

    Windshied Washer Fluid Disappeared??

    Thats what i was afraid of at first, but I went from a full windshield washer fluid reservoir to a bone dry one so I know where the fluid originated. There was a lot of fluid on the ground and in the engine bay and I had a full coolant reservoir, thankfully. Coolant levels and temp were...

    Windshied Washer Fluid Disappeared??

    In the past 2 days I drove 2,000 miles, AWD tahoe ran great the entire time through some nasty weather as well, averaged 16.2 mpg at 70-80mph most of the time. Decent for an AWD tahoe I guess. When I was refueling about 1700 miles in to the trip, I heard the sound of fluids draining. I looked...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Fixed my weeping trans cooler lines for $5, weren't a huge issue to begin with but just an annoyance and couldn't justify spending $200+ for new factory lines that would do it again in 5k miles.
