I have a 98 firebird and i'm getting a misfire #4 anda lot of exhaust when i start the car. this started after i changed the fuel pressure regulator.
How many coils on the 98 trans-am ws-6 and how to tell which may have failed?
Did you go back stock regulator? the misfire, need to pull plug and check, more and likely it is a bad coil.
