My 87 Fifth Avenue went into the mechanic for 'futzing' because I was having fuel problems.
(earlier this year).
This was the problem of me cracking the fuel pump and not using a wrench on it to tighten the line. Slight/slow leak and air getting into the lines. He replaced the fuel pump and rechecked the rest of my work.
I bring it home and we drive it occasionally but it seems to have a new shimmy in the front end.
Finally get schedules worked out to have someone follow me 45 miles to...
