Had a recent crack in the head of the Lancer 2094.

Got a new motor and changed all over and cars running but only on 2 cylinders.

The coils have all been tested and are fine.

the passenger side coil is working.

The drivers side coil is over heating and possibly effecting the cylinders??

When testing the power to the plugs. The drivers side power light is very bright. Whilst the passenger side (which is working) is very dull and coil remains cool.

Is it possible that the driverside coil is getting to much power causing it to overheat? And not fire cylinder?

Desperately need help. Can't afford an auto eleci

my thoughts

can you swap the coil packs to see if there is a change in which coil over heats ?

coil packs dont throw a code .. coil pack can test ok when cold ..overload or .. fail when hot
if you confirm the two cylinders not firing are used by the drivers side coil pack
pull those two spark plugs and check for spark

seems like it may require.you ... to replace drivers side coil pack
