My 98 XLT V6 SOHC is running well, more or less, the idle is not so smooth, but no rough neither... I think that it could be better
RPM about 700
I have 31x10.50R15 tires
With the new tires, the speedmeter have an 10% error, checked with GPS
50 MPH in dashboard, actual 55... I guess that in the odometer is the same thing
I did a few things trying to improve my mileage
- New thermostat, the truck reach service temp fast
- New o2 sensors (ebay chinese ones) no check engine light, but I don't know if there are some unread codes
- Upper intake manifold gasket
- PCV valve cleaning
- Acceleration body cleaning
- IAC valve cleaning
- Mass air flow sensor cleaning
In city the best average is 11 MPG, driving like a granny
I live in a small town, so short trips.
In high way, at 60MPH with crusier control, the average is 16MPG
Poor, uh?
