Sadly, the Fiero ended up being the marketplace victim of too many issues to get into here, and The General pulled the plug immediately after the 1988-model-year suspension redesign that made the Fiero the sports car it should have been all along.īut what if the plastic Pontiac had never suffered from the misery of the gnashy, pokey Iron Duke engine and had been built from the start with a screaming supercharged V6 making way better than 200 horsepower?

You will only need two connectors from the Fiero engine harness.
