In later models we'd check IAC if the engine likes to stall at low
speeds but runs well with throttle input. Toyota IACs aren't the best
around. See the Autozone guide below on IAC, and google on IAC
cleaning:

Also check your exhaust gas recirculation system. Too much exhaust gas
at idle can stall the engine, too:

Look under the distributor cap and make sure it's clean and dry. Some
(L4) have oil leaks that foul things up.
You should also try to pull any engine codes from the computer. Haynes
manual at your local parts store should be able to tell you how. Just
in case you have stored trouble codes.
The exhaust leak should be isolated. Where is it leaking? Or is it a
busted vacuum hose? The exhaust smells different now you said. Is it
using coolant now? I wonder if you have a busted head gasket. Earlier
Toyota V6s are famous for that.

Great info! Will check all of those- doesnt use coolant or smell like its
leaking coolant. It smooths out when up to speed but still much less
peppier than it was. The only time you dont notice the difference in
performance is once you are up to about 60 MPH. Thanx much for all the
tips. ignatz (bob)

If you notice that kind of performance degradation, might want to
check timing belt too. The belts starts to stretch around 50K miles,
and some 5SFE belts are know to be so loose as to slap the timing
cover.
Also add the thermostatic valve that helps the engine warm up. You
know, the usual suspects. The valve is operated by the temperature of
the coolant. Autozone's guide will take you through the steps.
