Has anyone resolved their ignition coil CEL issues? (P0351, P0352, etc.)

[Felix7007]

Guys, I'm not doing so good. Got P0352 and replaced the Ignition coil on the Cylinder closest to firewall or furthest from front bumper and to the right if standing in front of your vehicle. Couldn't make the code turn on for about a month. On an on ramp in 2nd gear at about 5,300RPM WOT it comes on. I'm going to replace the coil closest to the front bumper on the right side if standing in front of your vehicle as there seems to be some controversy on which Cylinder P0352 is associated with. I'm hoping I replaced the wrong coil the first time and this will fix it. I'm out of warranty, what do I do if this doesn't work and the CEL keeps coming on?

P0352 corresponds to cylinder 2, drivers side front. The one you replaced I assume is driver side rear, cylinder 3.

It's unfortunate that there's confusion around the cylinder numbers. It's actually deceptively simple, they're in order from front to back lol. The front most cylinder 1 is on the passenger side, 2 is driver front, etc. It's physical position.

Any updates on replacing the correct coil?

When my first engine shit the bed, it showed a coil cel when in fact it had lost a rocker. Lol

Just going to revive this thread real quick and see if there are any upgraded coils that will last or any solution to this problem. My frs threw P0353. went to a shop had it checked and cleared. week later threw it again while WOT going from 2nd to 3rd. I try to not pass 6K RPM now, so far so good. going to order new coil and replace the old one as soon as i can.
I am scared that im getting misfires but im not sure how to tell if I am.
also kinda sad that this happened since I wanted to start AutoX.

Coils should not be a problem for autoX. Its prolonged exposure to heat (like track sessions) that does them in. Altho I've had coils go on my very first lap on a session, it was probably already damaged by heat from previous sessions. Wrap the head (the part that sticks out when they are in the engine) in reflective gold tape, it seems to solve the problem for everyone I've seen so far.

I ended up replacing all 4 coils and wrapping them. Cheaper then the Cusco solution I was looking at. The tape is cheap, its getting to the parts that's a PIA.

Can someone put photograph of which part should be covered with tape?

French website but you can really just look at the pictures:

Edit: For a little explanation. That is the passenger side, the green circles are the bolts that hold the ECU in place, you need to take them away so that you can move it out of the way (you dont need to unplug, just put it over the engine or something so that you have space to work). The blue circles are the bolts that hold the coilpacks and the red circles are the connectors you need to unplug to take the coilpack out. After that you have a picture of a coilpack wrapped on reflective tape. Now, you dont have to take the coilpacks out, you put the tape over them while they are in, its a little bothersome but takes less time for the same result. For the driver side, I found removing the strut brace that goes to the firewall allows you to dip your arm in to reach the coils without removing anything else.

Ignore the rest of the post after the coilpack image, its for replacing injector seals which you dont have as a problem. Hope it helps

very very thanks!

So I'm going to replace my coil on the cylinder that keeps throwing the CEL. But I'm wondering if after I switch it can I run e85 since I hear it runs cooler than 95 octane. Would this be a way to help prevent another CEL later. I plan on tracking and autoX after the coil swap.


UPDATE: just replaced what I think is coil pack 3, or C, (the one closest to the passenger) I used an OEM coilpack with no extra heat shielding. seems like I can finally take my baby to red line without a CEL! I dont know if its a placebo but the car seems to run a little smoother now.
Next Update after a track day or if the issue comes back.

i want an update after you throw some e85 in this... bone stock i presume?

I threw a P0352 code at NJMP last weekend. It has been the first problem I have had with my heavily tracked 2013 FRS with 38k miles. I read through this thread and thanks for all the information. I found this image on the web I thought would be helpful for anyone that has this issue in the future.
