After a rebuild to this 1985 toyota 4x4, and after fixing all the air leaks,etc., the truck has absolutly no power....please help

My 1986 would leak. The HP and LP hose coonections to the compressor where lose. Tightened up and stopped most leaking. I added leak detector and found the LP fill connection Schrader valve seat was bad. Put in a new Schrader valve (bought off ebay for cheap- but a couple of extras) and all leaks stopped. Night not be compressor itself. Have a pro check the system for leaks.

how is the throwout bearing? Is it still there?
If you are bleeding it correctly with a power bleeder, master first then slave; I would be looking into the mechanical parts, like the bearing and yoke.

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. 

Check the idle air contol valve, you could also have a vacuum leak or a hose could be disconnected.

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)

Sounds like your master cylinder is shot. Go to a parking lot, stop, and pump the pedal a bunch of times. Then get out and see if there is any fluid leaks by any of the wheels. That would indicate a brake line leak. My first guess, however, is your master cylinder.

I think you must have the carburettor plunger not going well as you are getting flat spots under sudden acceleration, I think the best way to go is to get the carburettor overhauled.

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.

When the engine is running ragged, place your hand over the opening of the carburator. If the idle smooths out, you have a vacuum leak somewhere on the intake system; it could be the base gasket for the carb, the intake manifold gasket, or a broken vacuum line, or a combination of that. What you have is too much air getting into the engine, but the air is not going thru the carb. Please check for vacuum leaks, you can use a can of carb cleaner, spray the intake manifold, if the idle smooths up, that would be a good place to start.
