Low-rpm stumble with AC?

[jbrown1977]

I've noticed that my Cruiser seems to stumble when I've got the air conditioning on and I'm rolling to a stop. I've also had problems getting the car to start quickly. Could this be related to oxygenated gas, or do I need to get my ECM checked out?

When I was in Daytona and had the air on, I stopped at an Eckerd's real quick. When I came out and went to start the car, I had to crank it 2-3 times before it would start. I have noticed one other time after running the AC that when I got back in and started the car that it seemed to stumble for the first few seconds after starting.Both of these instanceswere after driving a short distance with the AC on and then turning the car off briefly and then re-starting.

No explanation.

Thanks, it seems like mine does the same thing...I wonder if the PCM wasn't configured to handle the extra load of the AC under certain conditions.

Check Plugs could have one that's fouled.
