Question about 1986 Toyota Pickup 4WD

1986 Toyota 4X4 22r Engine

I have a 1986 4X4 Toyota Truck with a 22r engine. When the engine is started the engine will not idle. If you run high rpm's while sitting still (not on road) the engine levels out & when I let off the gas it shuts off. When it does try to run it has a rough idle. What would you suggest to do to correct this problem? Is it the EGR Valve or carburetor? Thank you!

P.S. Is the fuel filter supposed to be full or small amount in bottom of filter? I noticed that there is not much fuel in the fuel filter, but the engine will start.

Hello;
It sounds as if you have a couple of possible problems. First could be the fuel pump. If yoou disconnect the fuel line, put the line in a jar and crank the engine over, you should get a pint in 15 seconds or so. Also check the pressure, should have around 5 psi. Secondly, you may have a vacuum hose cracked, broken, or leaking. Check your hoses and also the carbureator for leaks.
Hope this helps;
Thanks;

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

1986 Tercel 4wd. Car will keep running for a bit after I turn it off


If it chugs or sounds like a diesel, the idle speed could be too high, or you could have an excessive amount of carbon build up in the engine.

Vehicle: 1986 toyota "1 ton" pickup truck w/EFI L4 22-R engine. 245k miles After doing an ignition tune-up (plugs, wires, rotor, dist. cap, etc...), my rough idle issue has not subsided. Q: what should I...


I had a 1987 carburator truck and you are correct, dirt was the main issue. However, I think you may have the same issue, but in a different way. I would look at your fuel filer for starters and then run a can of injector cleaner through. If that does not help, maybe look at some new injectors. If you have 245K on this truck, I think your injectors may be tired and need to be replaced. It would appear that you have taken care of all the other issues. Another posibility is the throttle position sensor, (maybe)

Hope this was of some value.

Todd.

1984 toyota corolla 1.6 engine. How do i adjust


Carbureted models have a fast idle cam on the throttle,It is a screw that sets against a movable part,called the cam,when the engine heats up,the cam will drop upon tapping the gas pedal.Set the carb,while the engine is cold,by tapping the gas pedal,then adjust the fast idle cam screw by turning it in,with the engine running.Start out by turning the screw in a full turn before starting engine so it will run,then adjust the screw as the engine runs.
