New plugs, wires and coil packs on 2002 pontiac grand prix 3.8 v6. Now runs worse and looses power up hill. Correct firing order, all plugs properly gaped and wires secure.

It's not a coincidence that it runs bad now. Something went wrong during the tune up. It could be a cracked plug, damaged wire, cracked coil or bad firing order, etc.

I have the same car but when I turn the ac on the car shuts off, just had a new ignition switch installed, any ideas this is even confusing the guys at the repair shop.
