Yea I was looking at the throttle bodies from both and noted how much smaller the 90 was. Once I get the thing all together and running right, I'll change out the throttle body and see if my carefully calibrated seat-of-my-pants dyno will register a change.

 

From people who I know (or have read) who have done the throttle body swap and other air-intake-related mods, it is a noticeable change.

 

I had posted in this thread when it first started.

The title is "New Owner of Bronco II with bunches of problems".

I finally fixed all of the problems on my Bronco II, I sold it 2 weeks ago. Now it is the problem of someone else.

I had spent a lot of time and money getting things right, but with 218k miles, and needing a trans and driveshaft, I just took a bath on it and let it go.

 

It definitely seems doggy right now compared to my 87 Ranger, but I wanna make sure to get all the bugs worked out first. Then I can tinker!

I'm not planning on selling this one any time soon after all the trouble it took to get the darn thing! Thanks to the con man that sold it to us, we didn't get the title until a year later, from somebody else! Oh well. Its ours now and I still got a decent deal on it.
