This is what the coil towers should look like.
A common reason for misfires, hesitation, and
stumble is a corroded ignition coil and/or plug wire.
This example is from a 3.1 / 3.4 litre engine.
1- Burned / corroded coil tower
2- Burned / corroded plug wire
This can cause misfires under hard acceleration, or
when cruising at a steady speed (45-65 mph) then
accelerating to pass. Also will misfire at idle on wet,
damp mornings. Causes a code p0300.
|what can cause my coil to not have any fire after i replaced the engine.
|Well that depends on the car and engine. Changing the
engine would have nothing to do with it unless you did
not, or hooked something up incorrectly.
