Not the plug, coil, wiring,injector, no vacuum leak. Compression and leakdown test pass. What else?????
Here are some other possibilities to consider if your car is misfiring and you've already ruled out the usual suspects (spark plugs, coils, wires, injectors, vacuum leaks, compression and leakdown issues):
Faulty sensors: A malfunctioning sensor like the crankshaft position sensor (CKP) or camshaft position sensor (CMP) can throw off the engine timing and cause misfires.
Fuel pressure issues: Problems with the fuel pump, fuel filter or pressure regulator can prevent enough fuel from reaching the cylinders, leading to misfires.
Dirty or clogged fuel injectors: Even if the injectors themselves aren't completely failing, they might be dirty or clogged, causing inconsistent fuel delivery.
Exhaust system problems: A blocked or clogged catalytic converter can put excessive back pressure on the engine and lead to misfires.
Additionally:
PCM (Powertrain Control Module) issues: In rare cases, the engine computer itself might be faulty and sending incorrect signals that cause misfires.
Diagnosing these problems can be tricky and often requires specialized tools and expertise. If you've ruled out the common causes and your car is still misfiring, it's best to consult with a qualified mechanic to get a proper diagnosis.
