Well, the timing is dead on, so that was not the problem. The mechanic (he knows me, and I was not in a shop) stated that it could be a number of things, and it would probably be pretty expensive to take care of things. He said that I might as well drive it until it pretty much quits, then decide on ...

Well, I am a bit too used to topics expanding beyond their original purpose. Sorry about that.

I don't care if my opinions face opposition. I am fine with opposition as long as no administrative personnell discriminate aganist me for it (some forums have banned me for having a different opinion ...

Check out DBrown's 4.0L Swap

Ach! I don't know if I know how to do that, as I lack mechanical experience. :frown:

From DBrown:

if you have to pay for someone to swap in a 4.0L they are going to rape you on labor. you better find someone that can wire EFI also because that is the hardest part ...

yeah, that's kinda messed up. man, most of the people on here are ex militay or currently serving. personaly I may not agree with some of the reasons we used to go but if we are going we need to support period. I support and completely respect enyone that feels strong enough to go and risk there ...

I have never been enlisted, nor do I ever intend to enlist; my uncle hated every minute of his 4-year enlistment, and risking my life for the interests of a few oil barons and such is not my cup of tea.

You do realize, that's a pretty disrespectful thing say to those of use that have served, and ...

I'd do a 302 swap again in a heart beat. Heck I get 13-14 with No overdrive and 36's. But yes the 302 can be a can of worms, where you'll end up needing better tranny, and axles.

The 4.0L on the other hand is a good alternative. It will drop right in, and should improve milage.

The 4.0L must be ...

Well, the loosing coolant throws a red flag. Definately sounds like a head gasket issue, which certainly can affect mileage. Pull the plugs and see what they look like. They are the best indicator of how your engine is running.

Automatics generally get worse milage than a manual tranny.

I'm not ...

That's a pretty open ended question. Has there been a recent change in fuel economy? What engine, tranny and gears do you have? Tire size & and type?

I have a fuel-injected 2.9L V-6 with roughly 138,000 miles on it, automatic transmission (4-speed, I think), and I am not sure about the gears ...

My 1986 Bronco II is getting poor fuel economy (around 12-13 MPG). What is causing this? Bad ignition timing?

Sorry for this simple problem and question, as I am not heavily skilled in automotive mechanics.

I don't think that I need it, given that I don't use my current 125 MB E-mail all that much.

I have never been enlisted, nor do I ever intend to enlist; my uncle hated every minute of his 4-year enlistment, and risking my life for the interests of a few oil barons and such is not my cup of tea.

Well, that is not too bad, given that it only has a dent in the fender. Over here in Minnesota, they use too much salt on the roads in the winter. As a result, a lot of Bronco II's are rusty down here. I have a stock '86 Bronco II, and I have been combating rust. The rust is not too bad. It is just ...
