1985 toyota 4x4 pickup with 22re idleing to high, at 2000rpm and wont come down. What adjustments can be made to fuel injection system or anything else that might be the problem?

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. 

Try a new throttle position sensor or clean the plug going to it.

First step, see what is missing when it wont start, fuel, or spark. Is it carburated? or fuel injected. (22re should be injected.)

Sounds like you have a vacuum leak somewhere. There may be a stop adjustment on the throttle body, but usually high idles are due to unmetered air entering the system.

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)

Take car for trouble code at Autozone or similar store for free. it is probably the idle position sensor.(IPS)

is it a 22r or 22re?car or fuel injection?

check for a air leak in you sistem, or check for aditional idle screw adjust in the another end af the accelerator propel

Have you pulled out the spark plugs to see if there are any tell tale signs on them.They are a good indicator of many problems that occur and can save a lot of time isolating the problem.They should all be the same colour.Is the air box and lid properly secured with no leaks or splits in the intake tube.Have you put injector cleaner in the fuel tank to clear up any possible dirty injectors.Therse a few things your problem could be including engine vacuum leak which you can find by lightly spraying carburettor cleaner around suspect places such as inlet manifold and around injector seals.

the color of the plastic plug does not matter... You will have two injector plugs with white/red and yellow wires - those two go to cyl#'s 1 and 3.
the other two plugs will have white and blur wires.. those two plugs go to injectors # 2 and 4.
