I have now blown three coils in the last five months. When I bought the car it had aftermarket ign coils in it and the check engine light was on. I replaced the coils with Nissan ones. Two days later I blew the first one and put in one of my old aftermarket ones. It has now happened three times. I am only blowing the oem ones. I don't know if this is a coincidence but it seems like they just blow out under heavy acceleration. I am not squealing the tires or anything like that but just putting my foot in it. I have tested the other components and they all seem to check out. Anybody have any ideas? I am stumped

That sounds weird. Usually the aftermarket ones cause problems.

Like tosheto said, I would have expected the aftermarket ones to fail.

Talk to the dealer and see if they will get you warranty replacements. If the dealer won't do anything, call the Nissan zone office.

the aftermarket ones are causing harmonics in the harness and blowing out your OEMs?

I think that's why Nissan put the capacitor in the 12 volt supply line.

^^ It makes sense if he has mixed oem and aftermarket coils...ecu gets the signal back from the coils, if the oem and aftermarket coils are sending separate signals it could be overcompensating coils to try and regulate voltage. There aren't any capacitors between coil and ecu, right?

Makes sense to me anyway, I could be wrong.

Don't mix and match. If you go aftermarket, go all the way with 6 coils, not 3 OEM and 3 aftermarket.

I'm actually contemplating getting 6 aftermarket coils because I'm tried of guessing which used OEM coil is bad. I figured out one after 2 weeks but now I have another OEM coil that stumbles every so often. Nothing crazy, but freaking annoying.

His first post says he replaced the aftermarket coils with OEM. I think he meant all of them. This is an odd problem. Good luck

Somebody actually read the post. The reason the aftermarket ones are back in is I don't have the money to keep buying oem ones if they are going to keep blowing out.

2damax

Well if they blow out that fast you need to get them replaced for free man. Thats a shame on you. Don't be scared to make a scene if you must.

165donaldw

They said they are an electrical part and they won't do anything because they didn't put them in and I "must" have done it wrong. I guess I will just have to keep the aftermarket ones in.

Do you see anything in the engine bay that looks out of the ordinary? Maybe a ground kit? I don't disagree with ground kits, I actually have one on my car and put another one on a friend's car. But maybe this guy did something really wrong when installing it.
Take a picture of the engine bay and post it up here. Something tells me the previous owner did some shoddy electrical work....fixed it as best as he could, then sold the car to you. ignition coils just don't blow like that. On any Maxima.

Ah, yes, the old "you installed it wrong", but there's only one way to attach a connector. Fin stealerships.

Perhaps some bad coils throw from a moving car at some nice shiny cars on the lot will teach them a lesson LOL.

165donaldw

I tried to upload some pics but they didn't look good when they were up loaded. I don't see anything that looks out of the ordinary. They connectors look oem and the harness doesn't have any splices or weird taped up sections. As far as the ground kit what is that. Is that some aftermarket thing or just something people make up? where should I look for it and if it doesn't have it should I put it on? I have been driving it with these coils now since I started the post and it runs great but the F****** check engine light is still on. I just can't win.

Unless you reset it, the check engine light will stay on for several of what Nissan calls "drive cycles". Or you are getting random mis-fires. Have you read the codes?

165donaldw

I have erased it many times and gone through the trouble shooting for the codes and nothing seems to work. My Snap-on dealer even let me use his scan tool to go through it and see if I could find something but nothing out of the ordinary. I love the car I just wish I could figure it out.

DennisMik

What codes are you getting? P1320? P030x? Other? Let us know and maybe we can give you some additional guidance.

165donaldw

The only one I get is 1320.

Pilm

if you aren't feeling any misfires or getting a cylinder specific code (p030x), then most likely all you have is one of your aftermarket coils reading a little bit out of voltage spec and causing the ecu to signal CEL. you could just keep driving it and do nothing as long as you don't get a cylinder code or misfires, or you could play the replace one coil at a time and drive around for awhile and see if the CEL goes away game, which is what i did last time i had the generic P1320 code (i was lucky and got it on my first new coil).

165donaldw

The light did go out when I put in the new coils but I don't want to spend the money I don't have and blow them out again. I was just seeing if there could be something causing them to blow before I spend the money.

I misread the title to mean you replaced the ones the codes were for. Based on the emanage experiences people have had I would say that your issue might be from overpowering the coils during the time its not getting an ignition signal. If you dont have a piggyback that would be an ECU issue I would say. I would bet that the old owner had the same issue and they used cheaper coils and were just lucky that they "fixed" the problem.

My 03 has had this issue with bogging around mid throttle for the longest time. Light throttle it runs good man's hard but once you reach a certain point in the throttle its like it bogs down. Once rpms get past a certain point it runs hard again till red line. Never had a code or anything till yesterday. P0302 code popped up on scan tool. No check engine light though. I've been thinking coils might be problem and this code is first thing pointing to it I guess. Guess I'll wait till I can buy all 6 instead of just cylinder 2

165donaldw

What do you mean by piggyback. Is that something to add or check?

My car runs perfect except for the coils blowing.

Gemner

emanage ultimate is a piggyback, its basically an ECU that alters the signal to/from your stock ECU for tuning purposes. I would assume that the PO, if they have a piggyback in there, would have taken it out when the car was sold.

what happens with that is that the stock coils are not designed to receive a constant signal but with the emanage I guess there is a voltage "leak" which causes the coils to overheat and melt. The solution is to put diodes in the signal wire to prevent that power from going down the wire. I have never heard of this happening with an OEM ECU, so im just spitballing here

To follow Gemner's suggestion, look at the computer to see if it has been modified...it's inside the car. Sit in the front passenger seat and move your left foot to the left till you cant move it anymore. There it is at the very bottom of the dash.

Also look at this thread about an EU install;
