Hi. My 87 Reliant (2.5L) stalls when stopping, especially when colder.
Hesitates when running, and has low power and bad mileage. I got codes
33 and 34. As per a list of codes, they refer to AC and speed control,
but my car doesn't have AC not cruise. Anyboody knows of alternative
interpretations that may give me clues? Speed sensor maybe?

Thanks a lot
