Here's why:
* Fuel Injection System: The 1987 Fiero GT uses a multi-port fuel injection (MPI) system. This system injects fuel directly into each cylinder's intake manifold, eliminating the need for a cold start pipe.
* Cold Start Enrichment: Instead of a cold start pipe, the Fiero GT uses a cold start enrichment system. This system increases the amount of fuel delivered to the engine during cold starts, allowing the engine to warm up properly.
Understanding Cold Start Systems:
* Carburetor Systems: Older cars with carburetors often used a cold start pipe as a way to enrich the fuel mixture during cold starts. This pipe allowed extra fuel to be introduced into the intake manifold during cold starts, helping the engine start and warm up.
* Fuel Injection Systems: Modern vehicles with fuel injection systems typically use cold start enrichment features that electronically adjust the fuel delivery system for cold starts.
Therefore, the 1987 Pontiac Fiero GT does not have a cold start pipe. It uses a cold start enrichment system to handle cold starts.
