Need a datamaster log read & diagnosis help Friend of mine has a 94 Roadmaster w/ LT1 that is intermittently running very rough, mainly while in gear. Can someone please take a look at the datamaster file and see if they notice anything? I have zero experience with data logging or interpreting the results. The car is idling very rough for at least the second half of the recording.
Some background:
It's been running increasingly rough almost to the point of stalling. There is a very rich fuel smell coming from the tailpipes too. He has 1-2 exhaust manifold bolts broken on both sides but that has been the case long before the car started running like crap. Fuel mileage is consistently a few mpg lower than it used to be.
