I have plantar fasciitis is it bad to wear high heels?

No: Plantar fascitis may actually feel better in high heels.

Not necessarily: Some people actually don't have pain when wearing the heels as it takes tension off of the achilles' tendon. I would recommend you stay lower or at two inches. Any higher, and you put too much pressure on your knees. Stretching of the achilles would be important afterwards....

Yes and no.: The heels will take a strain off your achilles tendon, but will not be very supportive in the arch or rearfoot. A good supportive structured shoe is best when treating plantar fasciitis: think of it like a brace for the arch of your foot. Like with any injury, you want to brace the area as it heals, whether that's with a sling, cast, or in this case, a supportive athletic shoe. With orthotic.
