    problem with ECU part no. MD189548

    Good Day!

    I have a problem with my Galant V6 SOHC 2.0 24Valve... the 3 coils are new but it misfire there are only 4 pistons working, the 2 piston are not working.... I think the problem is in the ECU with part number MD189548... can the electrician fix it or i'm going to buy a new 1? 50/50 decision... any advice... can anyone help me.. please?

    First the cylinders that don't appear to work should be checked for compression, fuel, and spark. Then you can move to condemning the ECU.

    my mech check already the compression & the fuel, he said it ok.. i replace all 6 spark plugs but then nothing change.. i'm running rich coz in the exhaust i smell lot of fuel that did not burn..

    what do you mean condemn? change it to a new one?

    Condemn meaning blaming the ECU, he wanted you to check the other options he mentioned before "blaming" the ECU.
