Hi everyone, thanks for your help! I'm currently troubleshooting my 2000 Mercury Villager (3.3L 6-cylinder engine) which has a flashing Check Engine Light and several diagnostic trouble codes: P0325, P114
I'm experiencing a severe misfire in my 2000 Mercury Villager, but the MIL light doesn't illuminate. I connected an OBD-II scanner to the diagnostic port and only received a P1000 code (no data available). When I step on the throttle, the vehicle struggles significantly — it seems like it's using all its power just to move forward or backward. Could this be related to the same underlying issues? Any advice on diagnosing this without visible engine light activation?
A flashing Check Engine Light is a serious issue as it may indicate potential catalytic converter damage — especially with code P0302. Is this vehicle equipped with the 3.3L engine? I'd recommend starting with a fuel pressure test, followed by a KOEO (Key On, Engine Off) leak-down test to check for a stuck-open injector. Cylinder #6 is a prime suspect here. Next, verify spark at cylinder #6 using a plug reader — this can help identify if there's an ignition issue. If no spark is detected, use a noid light to confirm the injector is pulsing. A compression test should follow. Note: Cylinder #6 is located on the front bank driver’s side in this 3.3L engine configuration.
