Why does my Toyota 22R not idle at 1800rpm?
If idle varies, you have a leak there. Ok, here’s what I think is happening. When the engine warms, it opens the BVSV that allows vacuum to the Choke Pull Off. Once the choke pull off gets vacuum, that’s when the engine dies. If I pull the vacuum line off the choke and plug it, the engine runs fine, albeit at 1800rpm.
What happens when you start up a Toyota 22R?
The choke opens normally and the engine will fast idle at 1500 rpm after about a minute. About 5 minutes after startup it suddenly drops off and dies. It will restart immediately but the throttle has to be blipped to maintain.
Why is the solenoid not working on my Toyota 22R?
If you put power to that solenoid and nothing moves, it’s not working. You say it makes a clicking sound, so maybe it’s just stuck. Maybe try cleaning it really good and test it again. Some part of that solenoid should be touching the throttle. That is the part that should be moving.
What kind of engine does a pickup 22R have?
I have an 81 pickup 22R gas engine with the Aisin carb. Carb was just rebuilt using the NAPA rebuild kit. Carb was soaked in carb cleaner and all passages were blown out with the air compressor. It now starts easily, has great throttle response, and has more power.
When did Toyota change timing chain on 22R engine?
In 1983, Toyota swapped the dual-row timing chain used in older 22R engines for a single-row chain with plastic guides. In 1985, the 22R engine was redesigned, many parts from the newer 22R (such as cylinder head, block, pistons, the timing chain, and cover, water and oil pumps) are not compatible with those from the older pre-1985 engine.
What kind of carburetor does Toyota 22R have?
Cylinder bore and piston stroke are 92.0 mm (3.62 in) and 89.0 mm (3.5 in), respectively. The Toyota 22R engine has a carburetor fuel system and ignition system with a mechanical distributor. In 1983, Toyota swapped the dual-row timing chain used in older 22R engines for a single-row chain with plastic guides.
How to set carburetor to lean best idle setting?
The first thing to do is not set up the idle speed, but to set the Idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out.
