Re: loosing power on the highway - UPDATE
Thanks for the suggestions. I've gotten around to checking out everything. Nothing seemed to be wrong with any plugs, wires, filters, etc... I didn't dive as deep as to investigate a timing issue though.
While I had the hood up I figured I'd top off the fluids: The radiator was down considerably... About 2 quarts! [img]/wwwthreads_images/icons/blush.gif[/img] (oops..) Hasn't been running hot though... unless the temp gauge is broken - that would suck. The oil was almost due for a change, so I did that too. I never have quite as much used oil going back into the containers as I do coming out (old filter is always full) but this time it seemed a bit less used oil than usual...
Not sure what I did, but after the tinkering and changing the oil, the Bronco has been running noticeably better on the highway. Minor inclines that I had to drop out of OD would hold a steady 65 in OD like it used to! Although the real test will come next week running up and down the hills on i84.
Guess I gotta check the oil level more often... [img]/wwwthreads_images/icons/tongue.gif[/img] It does loose some (along with coolant apparently!), but it now seems to have been quite a bit more. This time it may have been down a quart after 2k? bad huh? I change it every 3k, but this time it was at 2200 since I knew I wouldn't have the time to do it later in the month.
On the side - I had also been noticing drive line vibration. I pulled the shaft and the Double Cardan joint was shot to pieces! Oh, it was BAD ... what used to be grease was now a fine powder and the needle bearings were everywhere!!! Anyway, I put a new one in and it runs smooth. I did this about a week prior to changing the oil. It didn't solve the highway problem, but did make the truck run smoother at all speeds in general. I do wonder if the bad joint helped contribute to the lack of power or at least the stuttering tranny like symptoms I had earlier.... hmmmm???
