This.Have you checked for a vacuum leak?
An intake gasket leak is just the thing to throw your idle quality off. Max vacuum, minimum fuel. Spray some WD40 in the area while the car's idling to see if it changes by ingesting the "fuel."Have you checked for a vacuum leak?
Not a rough idle; just a jittery idle. Wondering if new spark plugs would help.
Spark plugs have been in there since 04/18/2020. Daily driver. No check engine light.
And are you always supposed to change the wires when changing the spark plugs?
