I have a 2001 Ford Taurus SES that appears to "miss" at random times while accelerating the vehicle. This only seems to happen when the AC/Heat is turned on. When turned off, the missing doesn't happen/stops. Spark plugs have been changed among other things, and have had it to the repair shop at least 5 times and have been told every single time that they cannot find anything wrong with the car. They can feel what it's doing as well, but they have no solutions to offer me. Any suggestions would be appreciated.
