Hello I just bought a 1996 T100 4x4 and there are a few thing i was curious about but the first things i wanted to adress were the idle because after it warms up it idles at about 1300. What should it normally be idleing at because it sounds high? And how would I adjust this?

Also I got a check engine light and after a scan I got back P0130 and P0133. It doesnt seem to be running strange at all. Could it just be and 02 sensor?

THANK YOU

How many miles on the truck? Do you know if the O2 sensors have been replaced? If so, are they Denso or NGK branded ones? Could be they replaced the O2 sensors with Bosch...which doesn't seem to work very well with Toyota vehicles.

High idle could be a few things. How dirty is the throttle body (interior)? Could be the idle air control (IAC) valve is sticking or stuck. It's located under the throttle body and can be cleaned or you can replace it with a new part fer about $100 or so. Rock Auto is probably yer best bet fer a new one.

 

clean out your iac valve. pull it out spary the ˟˟˟˟ outta it with parts cleaner scrub it there is a little valve you gotta clean. let it dry out before plugging back in. should fix it. also check the throttle position sensor. a new one from checker is only like 70 bucks or so. they have a lifetime warranty had the exact same problem on my 98 t100 with 200,000 miles. idles perfect now.
