 Ford/Lincoln/Mercury PCMs suffer from coil issues. An important thing to note is that the coil packs and spark plugs have to be professionally replaced/repaired prior to re-installing the rebuilt PCM otherwise the faulty coil packs will burn the PCM again.

If you're having the notorious DTC codes for cylinder misfires P0351-P0356 then send in your PCM and we will fully diagnose and repair the unit. If you're having any other codes, please contact us first prior to sending it in.
