Looking for an E.C.M. car is running rough and when tapping on the unit it runs smooth for a short time, then back to rough.

ECM's usually sell for close to 2k make me an offer. Are you sure you need one they usually don't go bad.

I suggest first disconnecting the battery. Then carefully remove and reseat each electrical connector on the ECM - check for corrosion. Also remove and reseat the cal pack (chip). See if that helps before plunking down the money for another ECM.

Do you still need an ECM? If not, we will close the thread.
