misfire problems

I have an x type 2.5v6 and I've noticed slight misfire/ hesitancy at about 70 mph, but only when the air con is on... Can anyone help? Thanks

Darren the car is going to store a P code when there is a misfire detected, and even after its shut off, it'll be stored. You need to get the car scanned using an OBDII scanner, then come back, and post up your codes. With such an ambiguous symptom, there is truly no logical place to start. Sorry.
