Changed ONE coil (Cylinder 5)...BUT...
...since I changed the Cylinder 5 coil pack yesterday, it has eliminated the multiple cylinder misfires across BOTH banks!
Logically, I believe that they would be independently wired, but the frequent (several times daily), multiple cylinder misfire codes for the last few days have DISKAPPEARED and the car's running sweet as a nut! So...are the coil packs somehow linked? DailyMike. |

Interesting...thanks for the input! I should likely have mentioned that the car is run solely on LPG once it's warmed up to the required temp...about 60C I believe. At that point, I believe the Prinz LPG ECU would be in control? Mike. PS: Car STILL running sweet as a nut! I'll be doing about 400 miles tomorrow with my grandkids, so that'll be a good test... |
LPG ECU normally is not standalone unit but a piggy-back from the main ECU, main ECU calls all the shots if it does not tell injector to open LPG ECU will not open it.

My understanding of LPG ECUs is that they take the injector pulse signal from the car ECU and use that as its own injection trigger. The difference is that the LPG ECU will deliver a proportionately longer injection pulse as the engine requires more LPG than petrol. And of course it will be responsible for interrupting the signal to the petrol injector. |
