Quick Q: Anyone with these experience the following, and if so, recommended fix or direction to address?
Engine runs fine, on start and when warmed up, at idle or highway. CEL on idle. Gas pedal blip, goes away (but can and does come back). Stomp down test results in 1271 (ignition coil #1).
Other: All vacuum lines good, "mess under intake" mod done, ICV, AFM, TPS all functioning, no other issues.
