Talk about luck. After replacing my manifold gaskets my 171 went away. For good I thought. Been gone for a couple months. Started her up yesterday (warm start.... she was running about 30mins previous) and she bogged before wanting to cut out. Gave it some revs to keep it running and BLING.... CEL, 171.
I give up. Explosives might be in order now. The old dog is about to get taken "out back" out of frustration.
