P0106 Code
2006 Mercury Grand Marquis LS:
P0106 Code.
Idling rough / RPM fluctuating.
Already changed the EGR valve, Throttle position sensor and MAS. Performed a smoke check and no vacuum leaks that I can see. Also sprayed Carb cleaner around everything vacuum related while running to see if idle would increase but no change. Code saying it's the MAP but this year Marquis does not have one.
Anyone have a similar issue?
