hey guys i have a 92 yota pickup with the 22re motor, it idles like it has a vacuum leak but ive replaced all the vacuum hoses and the egr valve and it didnt fix it. any ideas? please let me know your help would be very appreciated

 

I'd check for vacuum leaks with an unlit propane torch. There are a few gaskets which could fail along the way: Throttle body gasket, Upper intake plenum gasket and lower intake gasket (attached to head).

Also its relatively common to find cracks in the intake tube that runs from the airbox to the throttle body.

Rough idle can also be caused by an inoperable idle air control valve and throttle positioning sensor.
Double check your TPS here:

Very simple, you just need an ohm meter and a few thickness gauges.

Then i'd go aand check valve clearance and timing. After all those check out, come back.

 

thanks for the help guys, it was a crack in the intake tube, replaced it today and shes runnin like new again!
