e 430 with miss
the car showed no codes and the check engine light has not come on. it acts likes it is idlig to low and feels like it has a monstrous cam in it. deffenently not smooth as it was before.
and it does this throughout the heat range,makes no difference if it is cold or hot. do these cars have a idle stabilizer valve...
and where is the peep hole/ access plate to see in the fuel tank.
