2003 Mitsubishi Eclipse Spyder GTS 6-Cylinder Frequently Shows P0300 Misfire Code After Complete Engine Component Replacement
I am now receiving a persistent P0300 diagnostic code on my 2003 Mitsubishi Eclipse Spyder GTS with a 6-cylinder engine. I have already replaced the intake manifold, installed new spark plugs, wires, fuel injectors, distributor, and both oxygen sensors. There are no detected vacuum leaks, and all EVAP system components have been replaced as well. The MAP sensor has also been replaced. Despite these comprehensive repairs, the P0300 code continues to appear. What other potential causes could be responsible for this recurring misfire issue in this model?
