Recently been having an issue with my civic. I'll be driving along fine for maybe 1/2 hour and the car with start running strange. Afrs will become leaner through the entire rpm range, car won't idle, loose all throttle response and power, and get a slight misfire. The car also throws a code 20 (Electrical load Detection). Often when this problem starts, the cel will turn off and then back on again for a second. If I shut the car off for 3-4 mins the problem goes away but starts again in about a half hour. Any idea what my issue could be or how I can go about troubleshooting the problem?
