Is it common to have a coil go out and not have a CEL?

Truck ran bad...changed plugs....then it ran great....while installing the plug i accidentally broke one of the coil connectors clip thingy so it would slip out every once and a while and it would drive like crap again and it would throw a code....well today i replaced the connector but it still runs like crap but doesnt throw a code.....think one of my coils is bad?

 

engine? sometimes fords are a PITA to get a cel from a misfire. most likely that cop/coil pack is no good.

 

2002 4.6

 

What color are the COP connector wires?

The ones coming from the truck are RED and GREEN....and the ones coming from the new COP connector is WHITE and BLACK???

 

the wires are part of the harness and i dont think they change colors i have no clue what your talking about.
are you talking about the new plug? if thats the case then just plug it into the cop and compare it to the other cop's. just look at the left wire and see which one is the left wire on another cop. and same with the right wire.

 

the wires on the OEM harness....one is green and one is red....and on the new harness that i need to splice....one is white and one is black....its a lil confusing haha

 

Coil connector wires have their specific color/stripe wires. None are identical in that harness.

What are trying to do ? or determine ?

The connector you show isn't part of that harness by wire color. That's not the way it works

Did you push the RED insert into the connector correctly? That clip locks the wires in place. Then you need the Foam/rubber insert pushed inside the connector as well. It will collect moisture quickly if you don't get it right.

Those connectors come apart, you know that right ? That's how you replace them. It's very easy, - faster and better than splicing.

 

ok sorry i had a little bit of a brain fart for a second.

 

Ok i think i installed it backward then....cuz i just matched up the new harness to the old harness and put whatever wire was on the left to the left and whatever wire was on the right to the right...if that makes sense....

 

My guess green=black?

 

Don't splice it yuh butcher

 

how much is it for a new set of plugs and a new coil... i have a 03 f150 fx4 with 52,xxx on it and check engine light just came on.

 

I paid $80 for all 8 of my coils....and i paid like $20 for my plugs

 

Memo12687, where did you get your coils from. I hear that Global sells decent coils. They have them on Ebay for $69.95 + $12 for shipping. Im thinking of going with a set of those.
