I have replaced all spark plugs, checked all coils for conductivity, and they all check good. The other thing is that my car is throwing a code for a random/ multiple cylinder misfire, i was wondering if this would be because of the fuel injectors? if so, is there any good step by step instructions out there to replace these because i have looked on VADIS and there is nothing good enough.

Thanks

 

I had a Land Rover that did this and it was caused by bad plug wires.

The way I found it was to run the vehicle at night in a very dark area. When I fired up the vehicle and popped the hood it looked like a little light show under there. Replaced the wires and all was good.

Not sure if you have replaced the wires or not. If not, check them out.

 

i have checked all the coils and they are sparking to the frame when i tested them, so i am assuming that if the coils are sparking to the frame that all of the wires are good enough, thank you and if you know of any other solutions i would be glad to check them out.

 

I also had spark, just not very efficient.
