Idle problem

2.4l 2rz m/t
When I'm driving my idle won't go back down unless I rev the engine, then It drops down real low. Does not stall.
No engine codes. I replaced the tps and tpms, but they were both carparts parts.
Any help would be much appreciated.

 

Possible vacuum leak.

 

I didn't see any last time I checked, but I will look again tomorrow morning. Could it be the vsv? The connector is broken, but it still stays plugged in.

 

Clean your idle air control valve, I bet it's sticking.

 

Yeah I just looked at the reviews on the iac I bought and everyone was having the same problems I am. I'm gonna test tomorrow, but I'm sure that's it smh.

 

It's the throttle body.

 

Is the throttle plate shaft binding on it’s pivot in the throttle body housing?

 

That would make sense... Can I lubricate the picot point? Would I need to replace the throttle body

 

*Pivot

 

Okay I understand I cannot do that now...anybody know if other Toyotas have compatible assemblies? Can I source a specific part of the tb?

 

You will probably have to take the TB off and see how much play is in it. I would get the part number for your TB and do a web search.
