Have had this rig for about 5 years it has 187K now, 10K miles ago spun #8 bearing, replaced crank, timing set, and intake valves, etc...
Engine runs great but gets 7.5 to 8.2 mpg. Possibly vacuum leak, but normally that includes a rough idle, but if vacuum issue so, where? Can smell gas in the exhaust.
Likely unrelated and typical: The TB light comes on when the brake is applied while the truck is moving at about 8 seconds, engine holds at about 500 rpm until brake is released, then goes up to about 750-800 which seems to be normal. If the truck stops fully before the 8 sec or brakes are pumped to reset the 8 sec, the TB light remains off.
Power in acceleration only in higher RPMs 4500 plus.
I really expected more from such a nice rig. Any suggestions where to check?
