Why does my 22RE idle up and down?
could be a vacuum leak or something like that causing it to race. most likely its you air mixture screw or the timing advanced too much. if you adjusted the idle on the actual throttle linkage on the idle screw you need to adjust the tps sensor to the correct specs.

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?
How can I tell if my 22RE engine is firing?
With the engine running pull a plug wire off at the DISTRIBUTOR CAP side one at a time. Start with the #1 plug wire and go around the cap clock wise to keep track. If the idle changes (drops) when you pull a plug wire, you can pretty much say that cylinder is firing.
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.
