Coil relocation gone terribly wrong; misfiring alot!

[GrandPrix34]

I recently relocated the coils to the upper portion on top of the radiator fan. Now I have some random misfires coming from the car.

 

I spliced all the wiring harness correct, but it is possible to get a misfire with an incorrect splice or better yet, off 2 wires that don't make contact?

 

One thing I noted that when I put the original wires on the car, it ran a bit better yet the wires were leaking current (visible in dark) yet the 8mm taylor wires do not leak current yet the car doesnt stay on as long..

 

When flooring it the car stumbles but gets the full range power uptop.

 

So in short:

 

1.) Can the car missfire because of incorrect splice on 5-wire harness or the other 2-wire harness that hook up to the ICM?

2.) Do I just need new wires?

3.) What do you think is up with the coil relocation and what should I have looked for?

do you have the correct firing order?

[GrandPrix34]

1-4, 6-3, 2-5 correct?

[maybe2fast]

why did you relocate? and is it a random misfire between cylinders? or just one cylinder

[digitaloutsider]

1-4, 6-3, 2-5 correct?

The actual "firing order" is 1-2-3-4-5-6.

do you have the correct firing order?

 

i'm wiilling to bet anything they aren't firing in the right order

[GrandPrix34]

so how do the wires go on the coils then?

 

Coil 1 -- Coil 2 -- Coil 3--

1 - 4 -- 6 - 3 -- 5 - 2 --

Coil 1 -- Coil 2 -- Coil 3--

1 - 4 -- 6 - 3 -- 5 - 2 --

 

The coil outline above that you typed is correct.

BTW, the cylinders on the engine itself are the following in case you got them mixed up:

 

front cylinder bank(radiator side) from left to right(facing the engine/front of the car)

2 4 6

 

rear cylinder bank(firewall side) left to right

1 3 5

 

Also, check your spark plug wire routing, improper routing can cause cross-firing.

well the misfires seem more random but evident. I'm going to change the spark plugs to hopefully get a better feel before having to buy new wires. I know the coils are good, I just don't know wat it can be...

 

How can i route the wires? I have a lot of wire left over! I'll try and post pics.

I may have read something about the crank sensor creating problems in coil relocation. Just a thought.

[GrandPrix34]

well I may have solved the problem by replacing the NGK V-power plus with some AC Delco plugs plus switching off 2 rear wires which were moister-laden. Ima run the car on the GTECH and see how much horsepower the coil relocation has given me 8)

 

J/K!!!!
