Having problems with my '98 Corolla 4 door. Engine light is lit up. When engine is cold the acceleration is OK, until you stop again, then it starts acting up. Acceleration is slow until you hit 20mph, then everthing is fine. I now have to shift to "L" lower gear, then shift it to regular drive after. I have an automatic transmission. Can anyone give a clue what I can do? Or how much this would cost to bring in? Thanks.
