My daughters 2005 Pt Cruiser Convertible Touring Edition has the 2.4 Turbo engine and automatic trans with 92000 miles on it. Two weeks ago it stalled on her and restarted fine and check engine light came on and stayed on. I was able to pull code #P2305 with my code reader. Alldata info was check plug wires and plugs for cracks or carbon tracking. I installed new Autolite wires and Platinum plugs and cleared codes. I noticed her car was turning over slow and I load tested the battery and it failed. I replaced the battery and sent her back out into the world. It ran great for two weeks no problems and yesterday it cut off twice. She said one time the rpm's shot up to 4500 for an instance and dropped back to normal. When it cuts off it will start back up no problem. It cut off once at traffic light and twice driving down the road. It is not setting any codes this time and check engine light did not come on. Any idea's where to look would be appreciated.
