I have 04 Intrepid ES 3.5L. Found codes P0340, P0344, P0430, P0420, P1776, P0871. Dodge Dealer replaced both CATS, four 02 Sensors, Pressure Sensor in trans (because of limp mode) and plugs were changed with factory suggested plugs about 1 month ago. Now car is misfiring like crazy, stalls and gas mileage has fallen to roughly 200 miles per tank from roughly 300 miles per tank and the engine light still on. I checked code myself by turning key 3 times and found code P0300 and dealer wants more $$$$$$ to check car out after already receiving just over $2k. The Car runs worse (engine wise) than it did before going to the dealer.
The good news is; car nolonger goes into limp mode. When I'm on the Hwy, this car runs, but if I give it too much excelleration at once, it wants to putter out. What's happening here? Any suggestions.
