The car is a 3.0L v6. I've had it for the last 30k miles with no major problems. Within the last few weeks now running it with the A/C on causes it to misfire. I've changed plugs, wires, cap and rotor air filter, PCV valve and fuel filter. I've checked the vacumm lines and all the hoses still feel soft. I believe they were replaced by the dealer I bought the car from. I didn't see any cracks or anything loose. Car runs great with A/C off. I'm in phoenix and that is not an option this time of year. Any Ideas?
