2007 Sonata idles rough when initially started
New member here....
Have a 2007 Sonata (2.4 L inline 4) and been plagued with rough/shaking car when initially started and pull to stop, and generally goes away when fully warmed up. Recently had oil change and service area switched me to a lower viscosity oil (5W30 to 5W20) and checked a solenoid and it was fine. Also did a fuel service treatment I suppose in an attempt to flush out stuff........I was a little surprised he didn't pursue talking about tuneing up aspects but maybe none of those codes flashed......a repeating code I do have is Code 11.........though I confess when the codes refer to emission stuff I sort of ignore them.......any thoughts welcome.

more like an oscillating idle when first started...up/down....near to stall...then warms up and is fine......been seeing some posts on EGR valve, timing tensioner. It was the timing control tensioner that was checked.........
