    2008 tahoe K1500. Throwing P0300(random misfire) and P0174 (lean bank 2).

    I just want to follow up, incase someone in the future runs into something similar. So after taking it to a few different places, I decided to have two bungs welded on the drivers side exhaust, and installed the O2 sensors that were hanging. Everything goes back to normal. It only costed me...

    I have one scheduled at the chevy dealership around the corner next Tuesday. I'll swap out the TB in the meantime and report back. Thanks for the replies

    It was coming from under/around the throttle body. No pinpoint. I should have inspected more

    2008 tahoe K1500. Throwing P0300(random misfire) and P0174 (lean bank 2).

    Ok.. so I threw the old coil and wires back on 2 and 8. I unplugged the battery for 10 mins, and touched the terminals together for a few seconds. Cranked it and it still runs bad. Very intense gas smell. I can hear the air not combusting and exiting the exhaust. It doesn't stall though. Idle...

    Yeah I can look at the data, I have a cheap scanner that can read live. What would I be looking for as far as fuel trims?

    2008 tahoe K1500. Throwing P0300(random misfire) and P0174 (lean bank 2).

    Thanks, I will swap it all back out tomorrow. I'm still just boggled by how the shop resets the throttle in the gizmo gadget, and everything goes haywire. I watched as he pressed the button, "throttle reset" and it all went berserk. If this truck had a tuner (which I suspect) could what he did...

    Tomorrow I'm going to pull the spark plug on the 2 and 8, the original culprits throwing codes, see what it looks like.... I've never seen those last 3 codes, those were caused when the shop plugged up the high-tech computer and reset the throttle. Maybe they'll go away? Thanks for the reply

    With the misfires before all of this, that originally threw p174 and p0300, the truck still ran good, just had some hiccups every few redlights.. Figured any information helps.

    2008 tahoe K1500. Throwing P0300(random misfire) and P0174 (lean bank 2).

    Ok so I had a smoke test done, and saw that the throttle body was leaky, so I replaced it, but it was still feeling the same at idle. Then i took it to a shop to look at the data and they said 2 and 8 were missing pretty bad. I replaced the coil and wire for both of those, cranked it and it...

    2008 tahoe K1500. Throwing P0300(random misfire) and P0174 (lean bank 2).

    5.3L 187,000 miles, it's throwing P0300 and P0174. Bank 2 would be passenger side? My thought was to check the spark plugs/coils, am I on the right path? Or is this code normally the fuel pressure regulator? Thanks for any help in advamce.

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    Would this cause a clunk, even if it isn't in 4wd? As far as the diff. Yeah, both have play. Should the bolts that touch the axle have a bushing? Or can I just tighten them?

    It's hard to hold the phone and push the hog up with one hand, but this is just to give you an idea how much play there is. With two hands, it doubles.

    Just wanted to throw in, oil has stayed the same since I added 3 qts. Pressure has been steady 40+. Will do complete change tomorrow.. payday. No leaks

    I did notice this, but there is no play, up, down, sideways, I did pull ups on it and nothing. This was the rear, at the transfer case, I believe... I'll have to check again.

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    So I -think- I know where the clunking may be coming from. I got under there, and I can literally push the front hog head up about half an inch. The mount bolts that the differential is attached to have play, so do the bushings where the mount bolts to frame.I have not used 4wd since I got the...

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    I added 1 more qt this morning, now it's showing an acceptable level. It's seeming as if the truck actually was almost completely empty... but the engine made no weird noise until the pressure went wonky, then tapping at idle made me check the oil. Engine still bone dry underneath. Crossing my...

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    I'll check for numbers, and do a change tomorrow. The tube seems to be where it should be, about 5 in. away from the tranny tube, pretty much parallel. I will add, it takes some push to get the dipstick all the way down. Maybe its catching on a flange and kind of snaking up? Its hard to tell...

    When you checked your fluid, was the engine warm or cold?

    2008 Tahoe LTZ. No oil. Added 2 quarts, dipstick still doesn't show anything.

    I bought the truck last friday, all seemed good. Today i noticed my oil pressure guage fluctuating and heard a light tapping. Checked the oil, it shows complete empty. I continued to add 1 qt, dipstick showed nothing, added 1 more qt, dipstick still dry. Nothing is leaking underneath, all is...

    Front Differential Carrier Bushings in Brackets Worn Out

    Hello, I recently bought a 2008 police tahoe, ltz, 180k miles. I hear a clunk/hard click when I am coming to a stop. It does it maybe 5 out of every 10 stops. Seems to come from right under the front driver side. Sometimes it does it when I go from P to R or D. Other than that noise, the tranny...
