03 c230 p0304 code help
Just got a p0304 code on 03 c230kompressor.
It idles rough but if you turn off the ignition and
then turn it back on, the rough idle goes away
for about a minute or so, then returns. I cleared the
fault code but it comes right back on when the
rough idle returns.
Is cylinder #4 at the back or front of the engine?
Any suggestions appreciated.
also the spark plugs have 74,000 miles but were checked okay 3 months ago when I had o2 sensors replaced.
