1999 4.0 4x4 XLT EXT. CAB 84k miles
I picked up this truck recently after it had been mostly sitting for most of 4 years. Only now am I able to get to service it but have driven it on errands - 148 miles total. First partial fueling was at 83075, 3 more partials then a full tank at 84223 miles with a can of Techron. It threw P0174 & P0171 at 84215.
So total...
Miles driven - 143
Gallons used 26.153
Gas cost - $56.89
According to 2 MPG calcs that's only 5.7 mpg. Fuelio says 10.9 but still, quite atrocious!
I finally have some time to service &/or replace the usual suspects.
-Air & Air Filter
-Spark Plugs/ plug wires
-Throttle Body / MAF / IAC Cleaning
-Check if fuel pump is weak?
-Clean egr valve
-Clean egr valve
-Injectors cleaning - for now techhron into a full tank
-Replace O2 sensors???
-Smoke check for air leaks in hose
-Brakes dragging (but I don't think so)
-Flush coolant, other fluids
-Check failed fan clutch
-Test engine compression
-Check restricted exhaust/CATs
Anything else or tips?
Not looking for great gas mileage but but normal 14 -18ish mpg range.
