Check there is no broken air lines or small cracks in the pipes spray carb cleaner around the air lines and see if the engine idling sound changes, any splits in the rubber connections replace. also clean out the air intake, can use the carb cleaner and get any dirt of the butterfly valves, check the colour of the dis cap white res on the pins clean them with some emery cloth so they are clean, check plug leads make sure there is no hard no flexy parts if stif replace. check the spark plug gap on the spark plugs, also check there colour these is a colour chart for spark plugs check and see what color yours are to the chart, this can tell you if your mix is correct or not. do this for now no part should be needed unless spark plug leads need replacing.

Just off the top of my head, guesses: Given what you've already done and the high mileage, could be carb, but I'd start with fuel filter and a good additive like Sea Foam. Also, you might want to replace the PCV and any other sensors which may be suspect.

Sounds like the distributor advance is sticking for some reason. Is it mechanical?

That is usaully the vacuum advance diaphram on the distributor. Its job to advance the distributor when at idle. The diaphrams inside rot and leak air, causing it not to advance. Take off the distributor cap and use a vacuum pump to individualy test each port (two of them) on the vacuum advance diaphram. You should see it pull back, if not replace it. They are sold at your local auto store, oddly its cheaper to get a whole distributor that has one for $100 that to get it alone for $150.

If it just started this after the tune up, you probably have a faulty spark plug.

Sputtered died


A 22r engine uses a carburetor, and a 22rec is fuel injected. If you have the fuel injected model, the throttle position sensor could be faulty.

1987 toyota truck, 22r, carb. sometimes goes into a mode where it


I had the same problem 3 weeks ago with my 87 Toyota truck. I posted the problem here and the response I got was- On the passenger side rear of the carburetor is a cold air idle valve, it has a two wire pigtail on it, remove the valve and clean it out with carb cleaner. Then screw it back in and all should be well. I did this, not really expecting much. My truck started right up and has been idling with no problem since. Try this and also your fuel filter.

Find the EGR valve and underneath the valve there are holes, with the engine running try to open the valve by using a scredriver, the engine should die. do it a few times to clean the valve.

You might check the PCV valve and grommet,I'm assuming it's EFI,if the valve isn't sealed tight it will cause the motor die at lower RPM's
