    Of course I did. I won't do that to a stranger let alone my grandkids. They're my pride and joy

    Suburban vs avalanche

    I only had a slight rear main seal leak. Would never do that to anyone and especially that's my grandkids. Would never ever do that to them.

    Suburban vs avalanche

    Yes they do. They're grandpa's babies anyway. I told them the extra accessories are mine so today will be swapping parts day so I'm off to the garage now to get things done. Once full swapped I will post pics of the new toy

    Suburban vs avalanche

    I went ahead and did the trade this evening. The issues with the avalanche is a purge solenoid and O2 sensor. So that's that. Nothing major and like you said my grand babies are actually worth it.

    Suburban vs avalanche

    I have a 05 suburban that I have an offer to trade on a 04 avalanche and was wonder thoughts. Mine have some issues and a few leaks vs the avalanche don't have as many issues. In fact it's my son in law and they have twins in the way along with a 3 and a 4 years old. That's why he wants to...

    2005 suburban 5.3 surging on highway under load

    I think it's due for tune up anyway. But since the O2 sensors need to be done in pairs I should do the other upstream one anyway

    2005 suburban 5.3 surging on highway under load

    So I tried something that I found online unplugged the MAF and tried driving without it plugged to see if it fixes the problem but no luck. Still acts the same way. So I guess plugs and O2 sensor is next

    2005 suburban 5.3 surging on highway under load

    I actually got the truck 6 months ago so history on it is not the best. I was thinking of putting plugs in but not sure about wires. Also bank one sensor 1 was bad so I replaced it. The misfire is on bank 2 and from everywhere I looked it's recommending replacing the O2 sensor on that side...

    2005 suburban 5.3 surging on highway under load

    So a new update. On my way to work today it did act up and finally threw 2 codes P0300 and P0306 which is cylinder 6 misfire. So any idea other than just a tune up ? The P0306 showing pending

    2005 suburban 5.3 surging on highway under load

    Well my next step is to test / check the MAF then tune up since it's due for it. I'm still a thousand from oil change so thinking about adding that blue devil now and see if does anything by then. But the issue is that I added STP about 2 weeks ago to the oil. Would that effect it or should I...

    2005 suburban 5.3 surging on highway under load

    Okay. Thank you. I was more curious if I need to change oil before adding it or after

    2005 suburban 5.3 surging on highway under load

    I've been looking into blue devil and was going to give it a try. And as far as the smoke it's like you said could be condensation. But since I put STP stop leak and smoke in it that's when it started. So considering blue devil since i have a bottle of it already but not sure if I must get oil...

    2005 suburban 5.3 surging on highway under load

    Okay and the smoke on stattup. Valve cover is 3 months old but only when it's cold out.

    2005 suburban 5.3 surging on highway under load

    Would it work for oil pan and rear main seal and should I get the rear main seal one of the stop leak ? I'm not losing coolant

    2005 suburban 5.3 surging on highway under load

    No overheating or coolant loss I'm only curious about what I can look at but coolant levels are good and only burns about 1qt oil between oil changes. But still thinking about running Blue devil in it since I have a rear main seal leak and honestly the smoke happened only once while it's 54...

    2005 suburban 5.3 surging on highway under load

    Does the intake manifold gasket on this engine cause coolant loss and or smoke at cold startup?

    2005 suburban 5.3 surging on highway under load

    started a few days ago while going on the highway once I give it gas to go faster it feels like it's missing or surging but no codes or any check engine light. So not sure where to start. But while cruising it's going fine especially going normal speed. I've done some research and it sounds...
