Hello, did you have this issue before replacing the spark plugs and coils? Will it continue to run if you hold down on the throttle? Any codes stored or check engine light on?
Customer: replied 2 years ago.
Did not have this issue,didntnreplace coils. If I hold throttle down it will run though roughly. Engine light is on but was on prior to changing plugs and wire

Ok , you might have a vacuum leak, left a vacuum hose such as to the pcv valve disconnected, if it didnt have the issue before. The coils are individual so shouldnt have an issue with them beins misrouted like a set of ignition wires off a single coil. Long as it ran ok prior to your work, I would double check everyything you were into while doing the tune up
