Default new to the 2.9

I'm familiar with the 3.0 found in the mid-90's rangers, but not 2.9. I feel as if I'm lacking power and I know I'm lacking mpg but not to sure where to start here. The plugs and wires look like they were replaced not too long ago. I'm wondering if the CAT could be blocked, I bring it up because I currently do not have a muffler and the truck isn't very loud at all... muffler coming soon. Also I don't have a Check Engine Light on.

It could very well be a plugged cat.
How many miles are on the Ranger?
It would be a good idea to get the codes read or spend the $30 or so for your own EEC-IV scanner, it will work through 95+ model year.
Before you go buying a cat, you can remove the cat and put a muffler in its place to see if that helps. Don't run your truck very far without the cat. There are many schools of thought on that subject, mine is, "it was put there for a reason and the ECM knows it should be there"
As far as the check engine light goes, the bulb could have been pulled, or burned out, it may not even have come with one, some years didn't. (someone will probably tell us whether it has that capability or not.)
I have an 86 2.9 in my B2, (at the present time, the 4.0 will be in it soon). I have been around these little engines for about 25 years, and like everything else, there are good and bad. If your engine isn't producing power and the cats are not plugged, with nothing else obvious, get another engine, 4.0 is a bolt in with a few modifications. The best part is, the 89-90 model year is real close to being a plug an play. If you decide to go that route, post it here and we will get you to places that have the info you will need. the other option, if you want to get more involved, is to put a 5.0 in it, again the same as above, and many of these guys believe a 5.0 is the only way to go.
Make up your own mind, and stay that course.

Thanks Ray, I'm definitely going to check the CAT when I can find the spare moment. As far as the Check-Engine-Light, I do have one and the bulb does work, i watch for it during ignition. I do have a pretty nice scanner that can read OBD1 up through the new can-bus systems, I just havent hooked it up since there was no light. You saying that that the 4.0 is almost plug and play is very intriguing... tax-time toy for me maybe?

I will come back and edit this later. But I read an article that a fellow with a 89 or 90 B2 wrote about how close the 89-90 RBV's were to the 1st generation Explorers. I can tell you this, side by side there is very little difference.
these links will help you in the future, the first is plug and play: http://www.broncoii-ranger.com/forum...hp?p=9135#9135
The second is Tech Info from that site: http://www.broncoii-ranger.com/forum...017975b60ebeac
This is the Tech Library at The Ranger Station, also useful for the old RBV's: http://www.therangerstation.com/tech_library/index.php

As people are getting away from the older RBV's to get newer stuff, it is important to watch for places you can post and find answers to the problems that arise in the older stuff.

I am rejuvenating an 86 B2 by swapping it over to everything from a 92 Explorer, (wiring, ECU, front and rear axles, manual trans, exhaust, and what ever else that goes with it. When completed, it will be a 1st generation Explorer with a 86 B2 body) I got a dash from a 90 B2 and the interior from an 89 for it. The heater and air from the 92 are in with the controls from the 90 matching perfectly.
I will find the article and post a link on this reply.

Ray
