Is the Check Engine Light showing?
Do you mean to say the engine would not go over 3500 rpm?
You mentioned it takes a while for it to stop, do you mean to say after ignition switch is turned off the engine keeps running, commonly known as dieseling?
There are a few possible causes for this problem and ECM is one of it.
1. Faulty Throttle Position Sensor
2. Clogged catalytic converter.
