Question about 1993 Toyota Corolla
Did what in a tuneup? If done yourself, are you sure everything is connected correctly? Spark plug leads?
Was it running OK before the tuneup?
Was the throttle/ throttle body touched at all?
Carbon can build up in the throttle body of the Corolla, which (will/ may) eventually interfere with the throttle butterfly seating properly. Too much air is available at idle, can cause rough running.
If the idle bypass air was "adjusted" at tuneup, maybe it was incorrectly done.
Did anyone change the spark setting?
