coil changing problem?

[2002v8]

ok so i had the check engine light come on, got the code e.c.t and it was the number 6 coil so i changed it but about 2.5km down the road the check engine light came on so i checked it again and its the same problem so i wiped the code and then it did it again. the spark pugs are fine i just changed them, is there a certain way to put the coils in? have i done anything wrong ? i looked it up and coil 6 is the one seconed from the front on the drivers side and thats the one i changed, any help?

The connectors often go bad. They become loose and cause a high resistance. It's possible the old coil is fine and you just need to splice on a new connector. Though bad connectors usually damage what they connect to. (Fuel pumps, coils etc..)
