Diagnosing a rough idle or check engine light on your classic GM V8? A faulty MAP (Manifold Absolute Pressure) sensor connector can cause all sorts of drivability problems. This pigtail connector from EFI Performance Wiring Inc (part #210-0103) is a direct replacement for the connector on your MAP sensor. It's designed for many GM TPI (Tuned Port Injection) and TBI (Throttle Body Injection) engines found in Camaros, Corvettes, and trucks from the 80s and 90s. If your original connector is cracked, brittle, or the wires are broken, this is your fix. It comes with a short length of wire, so you can splice it into your existing harness for a clean repair. A solid electrical connection is key for your engine computer to read the manifold pressure correctly. Stop chasing ghosts and replace that worn-out plug!
