Re: Possible intake gasket leak
x2 here. Did the wife's 2002 Tahoe 5.3L flex fuel two weeks ago. Hard starting, knocking in the extreme cold, and throwing codes P0174 and P0171. It wouldn't stumble with carb cleaner so I took a chance and replaced the intake gaskets with GM's teal replacements at $120 (OUCH). Runs like a champ. Mama's happy again.
