I think I'm having the same problem with my 1990 Corolla, 180K miles. The last tune up was March 2006. The check engine light is functioning but not on, and no codes when I checked, either (check engine light flashed continuously).
As I'm driving it, the car will occasionally run as normal, but only for a second or two.
I recently had the battery and alternator replaced, but everything seems to be working normally there.
How do I check the throttle position sensor?
