87 4runner keeps high rpm

I have a 22r 87 4runner with manual tranny, when I come to a stop my engine keeps a high rpm until I put a load on it or just gas it a little bit, how do I resolve this.

Dash pot is probably all out of whack or it could be the throttle needs adjusting.

I've had the same issue.

Could be a vacuum leak?

I checked all the vacuum lines no apparent leaks... I can start it and it will have the cold start high idle.. Which is normal upon startup... But every time I drive and let off the gas it will idle up or stay at a high idle... I can press the gas quickly and it will go away until I rev it up again and it will stay at high idle ... It does this every time I let of the gas...

What rpm are you sitting at? It is fuel injection right?

Yes fuel injection 22re... Regular idle is about 1000 and the high idle until I tap the gas after every time I use the throttle is 1400

My runner does the same thing. Well it just started doing it about two months ago. I'd love to hear what y'all think it is.

Is the throttle sticking slightly open? Cleaned the IAC? I believe 22re's have one…

My 88 22re efi does the same thing. Its off and on. I have asked this and people are saying to take a look at the throttle position sensor (TPS). Im planning on trying to fix the problem when I get a break in work.

I also had this problem and it was the dashpot. Just pull the hose on the tb that has the little plastic valve dangling at the end of it. If the problem's gone, there's your culprit. You can also adjust the little screw on the throttle higher or remove it so the dashpot spring doesn't depress anymore. It's not easily serviceable and I haven't found anyone that makes a new plastic valve so it's gone on my truck. Fortunately, I'm emissions exempt here.

My wife's truck did this (94 xtracab v6) we had to adjust throttle/idle speed to bring it back to 800rpm. Ran at 4000rpm when in park.
