So they switched them and at about 40 MPH the engine started shaking and the service engine light flashing for about a minute. The code came up saying that #3 cylinder was misfiring. They changed the plug and wiring and they still got the same code. They switched the vacuum lines back and it stopped. But now we have the same code again about the EGR valve and some stuck flap in the engine. Both have been checked out and they are fine. Any ideas?
have the same problem?
