So just yesterday I turned my AC on for the first time this year and my car started to struggle about 10 miles down the road. It started riding rough and then finally began to slow down completely when I pushed the gas. The CEL light came on and when I ran the diagnostic it came up with code P1166. I have done a little research about this code and it seems it can be either and Air flow problem or a Fuel restriction problem. This same thing happened last year for the first time, but my CEL light never came on so no shop could diagnose the problem, since I couldn't recreate the problem. Since then I have had no problems with the car until yesterday, although it does make a weird little cricket noise when I start the car. Do you have any suggestions about what it might be, or what a shop should be looking for, so they don't try to bull**** me. Thanks for any help.
