So I broke down and bought a decent hand held scanner. Here is some recorded data.

This is after I warmed the truck up (about 6 mins. after starting):

Very interesting results!

Captain?

 

Out of town since Thursday, sorry for the delay.

Consistently running rich on bank 2 at idle, and too lean at 2K rpm. I would suspect a partially stuck open injector on bank 2. What make and model scan tool did you get? Does it allow you to do the cylinder contribution test or an injector balance test?

 

Gosh I would have no idea what all that data meant.Curious about this scanner what kind is it and whats the cost?Thanks.
