Engine Performance problem
2006 Pontiac G6 6 cyl Front Wheel Drive Automatic 75000 miles
I have a 2006 pontiac g6 with only 75000 miles on it. I have recently purchased the car and it has run perfect up until last week. I noticed the problem when going up a gradual hill. The car hesitated at least three times before making it up the hill. I immediately took it to a shop the next day it has been at the shop for a week now. The check engine light has not come on but it is still having the same problem. The car also seems to lose power when I accelerate the engine on park when the rpm hits 4. What can be causing this. Cottmans auto service cant figure out the problem.
