It now no longer idles rough, accelerates fine, the ABS light went out and the speedo only has the original ‘flicker’ over 70mph as original. If you replaced the PSOM with a junkyard pull or put in a new unit you’ll have to go to a Ford dealer to have the mileage reset and also adjusted for your tire size.
