Need diagram of fuel injection for 85 4x4 22re

All the above is normal , except 2000rpm is a little high at idle . can be adjusted down to 1500rpm. the computer adjusts the engine speed . in drive the transmission loads up the engine idle drops to 1000rpm . in park engine unloaded rpm increase all normal.

Check all the vacumn hoses first ,its showing a 1985 model on here so is it a carb or mono point fuel injection ?

You don't say if the engine is carb or fuel injected.
If it has a carb, it could be sticking linkage for the fast idle to the choke.
If it is fuel injected it could be a faulty idle air control valve.
Or it could be something holding the throttle open like a binding cable.

if that 2000rpm is start up from cold,,,its still a bit high! but only a bit,,,should be nearer 1500rpm cold out of gear,,,,
when warm it should run at about 850---900rpm-----out of gear-
950rpm for an auto out of gear,,
in gear an auto will drop to about 850rpm so that the motor wont stall when holding the brakes down i would take the car back,, but they may wont it over night so they can set the revs up from cold,,i have a felling that auto choke is still playing up a bit

Alright, i have a 1987 Toyota 4x4. it has a 22RE full injected motor..it was able to run, but it was running rich, and idling pretty eratic..and then now..it only starts up..and dies. after like 5seconds. 

this truck doesnt have a carb, this has a throttle body, its fuel injected,there are no adjustments,every adjustment is done from the factory, the computer controls the idle,trying to raise the idle will throw the tps readings off,

Could be several things..
You might want to try chaging the pcv valve..
And the oxygen sensor..
Be sure your intake air filter is good..
Not to expensive to doo all this - and could very well be a fix..
Good way to start anyhow - and elliminate those items if it is not a fix...

Hope this helps !!
rate me good ;o)

NOT THE FUEL INJECTION,CUT IT DOWN BY ADJUSTIN TIMIN

Early Toyota fuel injection use a cold start injector, it only works when the engine is cold. It is located in the intake manifold. for the mean time you can turn up your idle by turning a flat head screw in your intake manifold counter clock wise . It could be a coolant temp switch for the injector that has gone bad also.

Sounds like both need the chocks ajusted or there sticking.
