I have a 2003 non turbo 5 speed, 69,000 miles. Just replaced cam position sensor after getting code 0344. Now will run over 2500 rpm ok and no trouble codes. But my mileage has gone from around 25 mpg to about 12 mpg or so. Runs rough. Plugs and wires and air filter were upgraded about 6k miles ago. This drop was very sudden, right after the sensor replacement. I assume something did not reset. Is it fuel mixture/timing/computer/crank sensor/o2 sensor....?????
I did not disconnect the battery when replacing sensor. Will try that tonight. Any other suggestions?
Thanks!
