Idle too low?
Disconnected the battery today, changed my fuel filter and fixed a wire on my passenger side O2 sensor. Battery was probably disconnected for about an hour. Reconnected it. Started the car. Idle was a little high at about 1100 in park. Backed the car out of the garage and left it running outside for awhile. I was cleaning up the garage and I heard it choking a bit so I went out to check the gauges. It was idling at about 800-900 in park. Dropped it into gear and the idle dropped to 500-600. The car is shuddering, and when I tried to drive it around the block, it was getting bogged down. How did this happen...?
