I have a 06 PT Cruiser with engine light on. It blinks when idling and solid when driving. Had the engine computer check. Says 2nd cylinder.I changed plugs twice on #2 and all others once. Replaced coil sensor. Reset computer each time. Light returns. Motor run a little rough. Put seafoam in gas and a little in oil. Light went out for a short time but returned next day. Is this a possibility of a sticky valve and an oil change would do the trick. Help
Take it to a autoparts store and have code erased for free.

We had it erased several times. Would this cause the engine to continue to run rough?

What codes are you getting?

Don't know code but read out said "#2 cylinder miss firing". Since last time we talked ran sea foam in oil and had changed. Unplugged battery to reset computer. Still have light on and runs rough at idle. What else can I do?

Check the #2 plug, look for carbon, or incorrect gap.
