My '98 AT SR5 from a stop (while in D, say at a stop light) is very weak and barely rolls when I let off the brake. I'm used to ever other AT car I've owned have a pretty strong roll, 5mph or so, when I release the brake (while in D). I have nearly 190,000 miles on the car and realize it's not new, but I've had other cars with as many miles that were much stronger. This isn't normal, is it?

Not sure how its "supposed" to be but my 96 has a lot of pull from a stop. How big are your tires?

VolVette

Yeah, that's what I'm used to- a good pull, 5 mph or so... But speed in drive when not hitting the gas is a slow walk.

My tires are not any larger than the stock tires.

I once had a CEL come on and it read a faulty 02 sensor but the CEL no longer is lit. Is is possible that the O2 is telling the engine to get less gas and that's why I have so little pull?

Check your brakes and calipers. My truck's a 5spd and I noticed that my truck stopped rolling when off the brake. Ended up being My master cylinder was not releasing properly. I've changed the master Twice in 2years because of this issue. I also had a caliper that would stick on and off.

I would say that my no throttle roll when I let off the brakes is weaker than other cars. I'm pretty sure my brakes release properly and roll freely.

If your idle speed is set low, that would do it.

Proper tranny fluid filled to the proper level?

I'm at least relieved that my thinking is consistent with some of you Toyota experts because I've looked into some of these thoughts.

-Brakes - checked and that isn't the issue. I really thought it was originally.

-Tranny - drained and replaced just to eliminate that potential.

-Idle speed - When cold, I think I'm around 1400 and when warm 900.

I really think the problem has to do with having not enough power. I am unsure why it doesn't have much power but I did give it a full tune-up about 18 months ago and that didn't really change anything. I'm unsure what type of gas mileage I should get but I get around 20mph (mostly highway). My next guess is excessive friction or problems at the differential.
