Exhaust fumes

[fetcher]

How is your gas tank is actually still hanging, and is the 1992 tank rusted out? For a 1992 I would inspect/ change the vacuum lines. A cracked line will mess up the MAP and you can run rich. Maybe old fuel system rubber and such were not made for alcohol. Too late, but I have a really good top for the early cars. It does not fit mine, but it looks much better made than what you can get today.
