hey guys,
I recently bought a brand new 89 f250 (new to me). miles unknown. 7.3L, 4x4, ZF 5speed tranny?, 4.10 gears. My tires are just under 30 inches tall. The problem is at highway speed, I'm hitting 2800-2900rpms. MPG suk. I figure I should be around 2000 on the tach. There's a chance that the speedo is a little slow. Haven't clocked it yet, just feels slow. I may have messed up on the calcs, but don't think so. I guess a previous owner could have replaced the gears in the rear, but doubtful. Any ideas?
A couple problems with the truck:
doors won't lock, not electrically and not manually(can't push them down).
Hard to start- have to pump the gas 10-15 times before trying to start and
then takes a good 10 seconds to catch.
LOOKS LIKE HELL.
MPG suk- I estimate the mpg's to be around 10-11. I will know when I check the odometer/speedo.
Brake light is on- Manual says may be vaccum problem, will check out soon.
Needs oil change, and tune-up.
This will be a daily driver in a couple of weeks(losing my company truck) What would yall do first if you just bought a truck like this? No money for upgrades, just preventive maintenance for now. May put some bigger tires on it to help with the mpg
Any help or advice yall could give me would be greatly appreciated.
