turbo 4 running rich.

not a stang, but Im looking at a 1987 turbo dodge shadow and its got a bad misfire. My buddy says its running rich and he wants more money to fix it. Im asking because Im sure someone here can help me get pointed in the right direction, as I know nothing about turbochargers (or dodges for that matter)

If it's misfiring, chances are the ignition is messed up. Get new plugs and wires, and check the timing. If it's running rich, maybe the fuel pressure is too high...?

thanks

Another thing to check is the oxygen sensor. That can also cause rich conditions.

ahh thats what I was afraid of. How much are they to replace? Im hoping its a fouled plug or a broken wire.

Not much, maybe say $40 or so.

ok, thanks. I just wasnt sure if it was some kind of funky turbo thing.
