I'm having a surging problem with my 90 Prelude SI. It has the 2.1 motor, 5-speed. This motor/trans is from a 91 Prelude that I installed in the 90. The motor has 123,000 miles on it. Starts up with a high idle and stays at about 2,000 rpm. After about two minutes the motor starts to surge from a high idle to a low idle and just keeps doing it. The service engine light does not come on so I don't have any codes to look for. I'm scratching my noggin' on this one. Any help what to look for would be appreciated. Thanks in advance.
