Possible Coil Pack Failure?


Recommended Posts

this is another thought of mine about what could possibly be wrong with my misfiring SC400 motor...

is misfires in crazy amounts, and at 40 mph or so under acceleration the engine misfires and shakes violently...now i was watching on youtube, and i found 2 videos that clearly display exactly what my engine is doing...

this is exactly what happens to my car at red lights and idling and during slow acceleration...the only difference is my tachometer doesnt do that...


in this video, the time frame im referring to the most is from 25 seconds til 35 seconds where you clearly hear the engine stumbling..that is the closest thing to what my SC4 motor does without actually taking you all for a test drive...please give some input.

thank you
