2010 Dodge Journey. Check engine light came on. Codes came up as Crankshaft and camshaft sensors replaced them all and replaced the coils and spark plugs car is still losing rpm's around 30 mph and wants to slow down and die out. Not sure what to do as the next step to try and figure out the issue. The codes were P0008 and P0009 and I replaced those sensors. The check engine light went out and then started back up again about 5 miles of driving the car. the check engine lights comes on and is blinking. Each time i have checked and the codes are different so i am replacing the items per the codes but doesn't seem to be fixing the problem. any insight would be greatly appreciated.
