Question about 1991 Toyota Corolla
There could be several causes for this. If I were you the first thing I would check is the timing. If the timing is off enough it could cause this. After timing is checked and/or adjusted the next thing I would check the MAP(Manifold Absolute Pressure) Sensor. I can't remeber if a 91 is fuel injected or carburated, but if it is carburated I would check the carb jets and up the idle adjustment just to see how it would run. Do you have a check engine light on in the car? If you do it's more than likely a sensor either the MAP or TPS(throttle position sensor). If you do not have a check engine light on it's got be timing or something else mechanically.
Here's a place to start.
Let me know about the check engine light and I can assist further.
Hope this helps
