2007 Kia Rio it had a misfire replaced spark plugs and 2 coils. Did compression test 145 -155 psi. It has a 1.6 L engine. Now it idles rough when warm, almost stalls. I'm wondering if it could be a Egr problem. Service light has not come on since replacing coils. Don't have a scanner to check for codes.
