I've got a 1990 245 with 195k miles on it. Recently I've noticed it driving very sluggishly. Like the tires were extremly low on air (their not). When I let off on the gas it slows down immediately, like a brake caliper is dragging. None are, I jacked it up and spun the tires, no brakes dragging.
And I've noticed a small drop in milage has happend. Engine oil and transmission (Auto) has been recently canged. I'm going to change the differential fluid as soon as it warms up a bit. Could this be the problem, it's never been changed as long as ive owned it. Two years.
Any ideas? I'm at a loss.
Thanks
Andrew
