P0171 P0174 Intake Gaskets??
My Taurus is still throwing 171 and 174 codes after properly cleaning the intake and doing a full tune up.
A mechanic I trust ran a full disgnostic and said the intake gaskets are leaking, which makes the computer think it's running lean for the amount of air....
Researching this forum it APPEARS that intake manifold gaskets (top and bottom) are somewhat common on 3.0L Vulcans.
Is this the case? He cautioned me that as they deteriorate, I might actuially suck part of the gasket and get meyself in for more problems, or burn up a piston and the problem progresses.
You guys have been 100% in my book on this forum and have saved me thousands. Is the mechanic on the mark, or are there other gremlins that I need to eliminate before dropping $500?
Many many thanks to all of you.
