Hi Scotty: I have a 2001 Mazda MPV DX V6 2.5L 2497CC V6 GAS DOHC and the engine it's idle and running rough, check engine it's on with a "random misfire code " ( it does not indicate a specific cylinder ) engine

vibrates and the van too; I checked the coil pack and I don't have a spark in coil # 3 and # 4 ( between the coil pack and the cable ) all

the rest is fine ( cables, coils, and spark plugs ), I'd been told my EMC its bad and I need to replace it so my questions are:

can I go to the junkyard and get another EMC unit from the same make and model like my vehicle and replace it?

can I send my unit to be repaired in some of the internet places that offer this kind of service?

can I just swap units like there was plug and play or do I need to reprogram the replacement unit?

I would really appreciate all your input and information about this and of course your recommendation on this issue Scotty since the dealer just charges a lot of money for this units.

Thank you in advance for your help.


you would have to reprogram the computer to make it work. NO ONE repairs those things correctly, so forget rebuilts. It really is a pro job these days to swap car computers out

Ok thanks for you expert advice Scotty
