Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.

Can I get the code numbers that are stored?

Is a misfire felt when driven?

So far this is looking like a possible computer coil output driver failure or a fuel pressure concern.

Sorry I don't have the code #'s and there is no misfire felt. It happens more when driving up hills and between 5th and 6th speed

Is there anyway you can get it scanned or observe a scan tool while its doing a power balance test?

Have you ran a compression test.

I need more useful information so you do not buy and install parts possibly not needed.
