If the check engine was calling for coil packs and you fixed it, then you have to cancel the check engine light with your scanner to see if it resets. If you don't have access to a scanner, disconnect the battery a few minutes. If you still get a check engine light, scan again for a code and fix accordingly. Sometime the light will reset itself after several "good" drive cycles but I'm impatient and would want to know if problems are fixed.
