Help... what could cause one side of the engine...

not to function. Anyone have a clue?

At times the car runs great and then suddenly only one side of the engine is working. One side works great all the time... the other side stops functioning and is totally doing nothing. If anyone knows a possibility, please give a suggestion.

Hi Keith,

Someone else had this problem and Tom advised that a common lead splits into two separate leads for each bank of plug mounted coils and one lead can become faulty.

Cheers, Trevor.

the smell of unburnt fuel when this happens.

That will be real easy to check out!!
Could it cause a code 37? left 02 sensor...

That was what I was thinking when you were talking to that other guy in the other thread. I believe YT is the one who discovered this issue on a car of his, maybe it was the SUS.

You need to be able to reproduce the problem. When it rears its ugly head again, you must test voltages on all the coils... Start there

How much voltage are we looking for, Tom?
Thanks,

Tom

is the black and white on both banks, right?

Does the two connect at a quick disconnect or just a wire splice?

Thanks,
Keith
