AC/Heat causes car to miss when turned on
Car runs great until you turn the climate control on. The car starts bucking/missing very badly. It's not as bad when the fan is on low but it's terrible on the other 3 settings. Has anyone experienced this before?

The brushes in the fan motor may be shot. This causes a lot of electrical noise in the system which foo-bars the sensor values and ECM response.

It turns out that the wipers and blower motor kept turning off together. It has a wiring issue that I've found so I think that's the problem. Will try to post a pic when the weather clears up
