i have a 95 contour and i got a code 556 and the other one was a 332 and 327 i think. something about the egr valve not opening and the 556 was the fuel pump relay. my question is can i clean the egr valve? i know i need to change the fuel pump relay thats why my light is going on kinda jerks alittle then goes back off.
