idle rpm dropped all of a sudden
i have a 1991 4 runner, yesterday i noticed that my rpm have gone down to about 500 at idle, and it's idling rougher. since i got it it has purred like a kitten until now. Fuel filter?

You can always turn up the idle....theres a screw on the throttle body. Wait...what engine do you have?
I know where the idle adjustment screw is on the 3vz (v6) but not the 22re (I4).

Yeah adjust your idle screw. Could be that with this recent temp change it needs to be bumped up, I don't know where you live but I'm in nc and we just started gettin hot weather and I had to adjust mine because of this

PCV valve is a pain on the 3vz if your scared to take off the plenum.
But If you wanna turn up your idle a little bit, looking at the throttle body from the front of the truck, theres a screw, uh...ill put up a pic for ya. hold on a sec.

Start the truck. Screwing it in lowers the idle, screwing it out raises it. I believe. Youll know when you do it. You want the idle to be 850-950 when warm, so make sure the engine is warmed up.
