Mitsubishi Eclipse P1400 Diagnostic Code: Causes and Fixes for Power Loss at 3000 RPM

Model: Eclipse Fault Code: P1400 Posted: 2006-06-13 12:14

My 1998 Mitsubishi Eclipse GST has developed a check engine light, and the diagnostic tool returned code P1400. This specific fault code is model-specific and relates to the fuel system pressure regulation. The car now loses power after reaching 3000 RPM and exhibits a fluttering sensation during acceleration. I'm looking for accurate information on what P1400 means and how to resolve it. Any insights or step-by-step fixes would be greatly appreciated. Thanks, Jax.
