I just got my car frost tuned which I am pleased w/. After driving about 100 miles I got an ses light p0343 cam sensor which Autozone reset for me. Then after driving on the highwaymy tach would stop working and after a bit would jump back to life. Also, when the car hits second gear I feel the gas pedal smack the bottom of my foot (if that makes sense. The car is also idling a lil rough. I then got a p1404 egr code. Im told you can clean the egr? Is this advisable? Which part do I start w/ or do I need both? Sorry for the long wind.
