What should I look for in a 22RE engine?
I get dozens of calls every day with people trying to diagnose various issues with their 22R / 22RE / 22RTE engines. Everything from hard start issues, rough idle, mis-fire, lack of power….blah, blah, blah. Since there are a few hundred things it CAN be, I recommend starting with the basic stuff first.
What was the problem with the Toyota 22RE engine?
There was an internal bulletin for Toyota factory technicians back in the mid 80’s about a similar issue with 22RE engines. The issue was an internal programming problem with the ECU.
What should the idle speed be on a 22RE?
We also recommend going a hair tighter than the factory says too. .007” on the intake and .011” on the exhaust side. If it’s your first time adjusting valves, TAKE YOUR TIME AND TRIPLE CHECK YOUR WORK. It’s not rocket surgery, but if it’s not done correctly, things can get ugly quick. Rough idle? Engine shakes at idle? Low idle?
What happens if you dont set the timing on your 22R?
Not setting your 22R/22RE timing properly can lead to very poor performance, bad gas mileage and SEVERE engine damage. Don’t mess around. Once It’s up to normal operating temp, you can now set the timing with a timing light. Grab a paper clip and straighten it out and then bend it to a “U” shape.
Is there a factory service manual for 22RE?
This is to be used as a basic guideline to start with diagnostics, there is no substitute for a FACTORY SERVICE MANUAL. That has the most detailed and correct info for your year of 22R/22RE/22RTE. Aftermarket manuals can sometimes lead you down the wrong path since they are written for a year range of 10+ years or more.
Is there an aftermarket manual for 22R / 22RE?
That has the most detailed and correct info for your year of 22R/22RE/22RTE. Aftermarket manuals can sometimes lead you down the wrong path since they are written for a year range of 10+ years or more. They can only give you simple info (and sometimes, the wrong info).
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.
How does the air flow meter work on a Toyota 22RE?
As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, the throttle body and the fuel injector. The air flow meter uses a flapper vane and temperature sensor to detect the amount and temperature of the incoming air flow.
When to test your cold start injector switch?
test yours before buying….. If your trucks cranks excessively (more than a few seconds) when it is cold, and you don’t get “fast idle”, check this switch. Most people seem to think it’s the actual cold start injector that failed, but 98% of the time it’s this switch that has failed. It is the most common reason for both problems.
