Default Funny-acting acceleration.

First off, its sad to see that the Toyota forums are so dead This is the first one I've owned, and I'm definitely impressed with it.



But anyways, I'm starting to drive my Toy around because the trans in my daily is taking a dump.

So I find that when I get on the road and start accelerating through the gears, it doesnt rev very fast at first, but once it hits a certain RPM, couldnt tell you what RPM because I dont have a tach yet, but it suddenly comes alive and has no problem accelerating. It does this in all gears as far as I can tell.

Its a 22RE, 5 speed manual, stock 4.10's on 33's, so I know its going to be a slug, but it seems odd to me that it will accelerate great after a certain RPM.

If I have to, I will get video tomorrow after I get out of work.

What year is it? I dont know much about fuel injection, But could it be a throttle position sensor?

BTW. the forum is dead for a few reasons. nothings broken, or salt on the roads keeps 30+ year old trucks in the garage.

The truck is an 84, but the motor came from another newer truck, I couldnt tell you the year or anything. If you know where to find some numbers on it, I might be able to.

This morning it was acting pretty normal though.

Do you want some better gearing? I'll trade you my 4.30 thirds for your 4.10s. That should turn 33s a little better.

I would, but I wanna keep the high pinion front. I'll probably go with 5.29's like you told me to because I'd like to run 35's.

So do you just think is basicly the torque curve of these motors coupled with too high of gears thats causing it?

I forgot you have the high-pinion.

I doubt the gearing is all that's wrong, but it's a likely cause. Once you get to the (relative) power of the operating revs, it would make sense for it to run better and accelerate more smoothly. I've never driven a Toyota with anything other than 5.29s and 35s, so I'm not much help. Have you gone about a basic tune up yet? Probably a wise investment.

I would go over it anyway. Although I was amazed at how little electrode my old XtraCab was running on when I got around to tuning it up after I had it a while. It would bog trying to go up hills on the highway. I was running 31x11.50 Yokohama Muddiggers on it. Not to mention the plug wires were kinda fooked.
