Re: 97 3500 454 4x4 project

I've been checking my mileage and it has been consistently 9mpg.
I suspected my fuel pressure regulator diaphragm was leaking too, it randomly would stall while driving, sometimes starting back sometimes requiring several hours, so I ordered new injectors from 5O Motorsports and a new AC Delco fpr.
Spent half a day changing them out, I didn't break any of the tabs on the rail thankfully.
Got her back together and sounded awesome. Ran to town for gas and a test ride then noticed a lope at idle when I pulled into the station.
On the way home it died the same way as before.
Suppose I am going to have to buy a decent code reader.
