Question about 1986 Toyota 4Runner

1 Answer

My 86 toyota 4runner runs great at idle, but when I go to drive it, (with the truck in gear) and the peddle to the floor it wont go more than 10mph. What would cause this?

And as soon as you push in the clutch or put it in neutral it picks back up.

SOURCE: Hydraulic Clutch Problem in an 82 Toyota Pickup

If you are leaking fluid from the clutch master cylinder then you have air in the system. You could try and bleed the air out of the clutch slave cylinder to get the gears but it would not last. The only way is to replace the defective master cylinder, replace all of the fluid and bleed out the air through the slave cylinder.

SOURCE: 86 toyota 4runner idles low and has half the power

Ok, there are four problem spots that i recommend inspecting the first would be the air filter.

The air filter may be clogged or dirty. this can decrease the power out put and it can also affect the idle as well. the next check point would be inspecting the spark plugs. make sue the plugs are correctly gapped and are not fouled in anyway. if they are fouled or incorrectly gapped, this will cause the symptoms you are experiencing at this time. Another check point will be the wire set(spark plug wires). make sure the wires are in good condition. remove all wires from the plugs and look inside the wire head t inspect the contacts. they should be nice and clean.if the wires are worn, replace them accordingly. the final check point will be checking the PCV valve. this valve is located Under hood, center, upper engine area, top of engine, mounted in valve cover. the testing procedure to be preformed on this specific device is stated below.


PCV VALVE TESTING PROCEDURE---

# Check the ventilation hoses and lines for leaks or clogging. Clean or replace as necessary.

# Locate the PCV valve in the cylinder head cover and remove it by pulling it upward.

# Blow into the crankcase end of the valve. There should be free passage of air through the valve.

# Blow into the intake manifold end of the valve. There should be little or no passage of air through the valve.

# If the PCV valve failed either of the preceding two checks, it will require replacement.


You will find the problem for you erratic or low idle in the areas above.

Please rate and god bless:)

SOURCE: 91 toyota 4runner 3.0L has very rouh idle, hard

All "TUNE UP' Components MUST Be Eliminated as suspect to go further with Diagnosis. They Should be 1. KNOWN to be or CLOSE to NEW or 2. Recently Replaced.
What you have is Obviously a Engine Performance Related Problem, Thus These Items Must be in very good condition when checking for a Problem here

Fuel not flowing as it should. 86 Corolla


Check the fuel pump pressure using a fuel pump pressure guage. It would not necessarily be unheard of to have a new, but bad, fuel pump. No or low pressure, then take the pump back and get another one.
