sporatic missfire
i have a 22re in my 86 4 runner and i have just completely adjusted the timing (chain and dist). i still have this regular but random miss going on... has ne one had this prob be 4. i was told it could be bad wires in my electrical system or sensors. my check engine light i know works but it is not on, so i am skeptical about it being a sensor, but would love some input from ne one that has had a problem like this before

sparkplugs and wires ?

My check engine light comes on for only a few seconds and then turns off in my 87. I have the same problem. It is the O2 sensor in mine. I usually just take it out and clean it up and the problem is gone for about 6 months or so.
