Idle stumbling and getting misfire codes on cylinder 1/3
07 sportage 2.0l has been having intermittent issues with stumbling at idle and on initial acceleration. Started with misfire codes so I replaced the coil packs now I'm getting the misfire codes plus p0011. I put my scan to on it and drive around and it looks like when it is stumbling/stalling the spark advance is going negative? If the spark advance stays between 6 to 8 the car runs fine.
