    P0171 & Check Engine Light, No Misses or issues

    I think I found the P0171 problem? 11/17/23 MILEAGE today– 191,577 Found air intake hose had popped loose. I last tightened it on 8/21/23 @ 190,200 after cleaning MAP sensor. So, I spray cleaned the MAP sensor and reconnected hose. Cleared P0171 code.

    Excessive Cranking/Transmission Issue

    Sounds flooded to me. If you try to force more fuel in after gas pump clicks off the first time can ruin the vapor cannister purge valve on intake (AC Delco # 214-1680) and/or the rear charcoal cannister. Or leaky fuel injector(s). Next time you go to start it put the gas pedal too the floor...

    Cooling issue

    I never have issues burping mine. Sounds like a blown head gasket or cracked head. Over heating it can crack stuff.

    Want to take my 2010 Yukon XL Denali with 180,000 miles for a family trip from Michigan To Florida - Can you help me make this a success!

    Are the valve body seals a culprit with converter failures?

    Almost 5 yrs ago at 130k miles, I installed a TC and a few associated seals/o-rings as preventative mx. Its still going strong today at 192k miles. https://www.tahoeyukonforum.com/threads/rear-main-seal-job-pan-etc-07-yukon-denali-6-2.108334/page-3#post-1293118
