Hey i was wondering if anybody could anwser this question: my engine has 2 ignition coils, and b went bad, but i have no idea which one is b. Help?

 

I would guess that Ignition b would be the one with the wires running to the intake side of the engine.

just a guess.

 

i hope your right. i just had one replaced and got worried it was defective. thank you.

 

my guess for B is also the driver-side(intake)

that is the side that ignites on the exhaust stroke......on cold starts it will not even fire...........if that was the one that got replaced the truck should have still started and ran.....

 

it wasnt, but then i switched and cleared the code it came back. i found that the ground was also slightly oxidized. i cleaned it and im waitin to see what it does. thank you tho

 

If that fixes it throw some dialectic grease on there. It will keep it nice.

 

i have done that and my code came back. im starting to think its resistor that is right before my ground. i'm gonna try doing a voltage drop test and see what happens

 

my truck spudders on acceleration in 3rd & 4th gear. I've replaced all the plugs and wires but not the coil packs. Starts up just fine and doesn't act up while idling. I was going to check the ground and connections to make sure they are corroded. any other suggestions would be great help

 

Take the old coil pack to an auto parts store and have them bench test it before you spend more money on parts. Also, you indicated that you have a trouble code. Post it here and we can be of more help to you.

 

Fires on the exhaust stroke. Um that doesn't even make sense. Both coils packs are waste spark, so they BOTH fire on both the intake and exhaust stroke.

It is true though that only one coil pack fires during startup.
