My intrepid mpg went down from 29 mpg to 24 mpg. The engine light came and the shop told me the code said that cylinder no. 1 was misfiring. They said I needed new plugs and wires and my injectors cleaned. I had all this done and it did not stop the problem. They switched fuel injectors and coils from other cylinders and the engine light still came on with the same code and the mpg is still 24. The engine idles rough and when I have the cruise set it will surge maybe 25 to 30 rpm. Enough you can feel it. Also, after you drive it 50 miles or so and the engine is warmed up, if you stop at a light and idle the engine oil light will flash as the engine idles rough. If you speed up the motor just slightly this stops. The engine light came back on and I had it reset. I have driven it about 200 miles and it hasn't come back on but the other problems are still there.
