Car has a miss at idle/low speed, seems to go away when you accelerate. CEL codes showed p0300,0301,0303,0305. Replaced plugs and wires. Plugs on rear bank, cylinders 1, 3, 5 I believe, were black, front plugs were nice and clean. After replacing plugs/wires car ran better for a few minutes then started missing again and CEL came back on with the same codes. Could the O2 sensor on the rear bank be the problem? It does not show a code for the O2 sensor. Any suggestions appreciated.
have the same problem?
