Low RPM P0303 code - Misfiring Cylinder 3 under 1000 RPMs
At low RPMs the car was shuddering and appears to run normally at higher RPMs. I
have performed a tune up, but this did not fix the problem. I have heard this could be
valve related, and I was curious if this is something that should be done by a mechanic,
or if i need to have all of the valves taken care of, or just the ones that affect cylinder 3?
Thanks!
