they should shove that 380 dollar invoice up their ass lol sounds funny. Hope u fix it urself.

 

make them prove to you how and why the coil packs went bad from the plugs

i also just remembered hack has a 2.2 so he just has the casette instead of the individual ones

 

I know I swapped the plugs myself, lol

 

Ah, I thought they all had the coil on plug arrangement.

I 100% guarentee the plug did not cause the problem.

 

I honestly don't think it'd be too hard to prove that, especially since they are fouled out

 

They know full well that the plug didn't cause the problem. It's just an easy scape goat for something they don't understand. Make them show you in the tech data that only ONE type of plug can be used on the car. The term *recommended* doesn't mean it's the one and only.

 

You think it's worth fighting after I agreed to let them work on my car?

 

Well if it could be under warranty, it would save you a good chunk of change.

Both times it happend to me the dealer fixed it no questions asked, even when I had my intake and 3" pulley installed.

 

i would you cant loose anything if you do

 

They just called back. They said the total is 409.12

 

pitch a fit about it being 100 higher than quoted

 

forget that. just do it urself like u said, junkyard and go to auto store for plugs

 

Damn dude, it might be too late to try to get that under warranty. You should at least make them explain how an aftermarket plug can cause a coil pack to go bad.

 

Wouldn't a fouled plug cause the coil to go bad?

 

I dont see how.

 

Sounds like a spark issue. Did you check your spark plugs?

and what recent modifications have you made?

 

No recent modifications, not in about 5-10k miles.

And the spark plugs have been in the car for damn near 15k now.

I never checked the spark plugs because they were ungappable and I wasn't doing any tuning

 

Find out what caused the plug to foul, other than that it is a specific brand. Plugs usually foul because of oil leaking into the cylinder or so much fuel being dumped into the cylinder that it doesn't get a chance to burn off. Or inefficient spark, like NJHK said.

They should also have checked to see if you have an injector stuck open.

They also should have checked all the connections to the coils to make sure they all have correct power going to them.

 

I had the same exact problem. I posted this about 2.5 months ago https://www.cobaltss.net/forums/problems-service-maintenance-69/car-wouldnt-start-first-now-runs-very-rough-74192/ They told me it was my platinum 4 plugs that made my coilpack module go bad. I had it fixed twice now. First time it happened they didnt know why. Then 2 months later it did it again and they said it was the plugs and it would ruin my warranty but they said they would let it slide if I put the stock plugs back it. It has been a couple weeks now so I guess I will find out if it dies again in another month

When this happened to me they said the platinum 4 plugs were to hot for the coilpack to handle. Which caused it to overheat then after it cools it stops working. Thats what they told me so I dont know.

 

Something tells me you should fight this. Spark plugs are a maintenance product right? So like oil, filters, tires, etc... its your responsibility to change them when due. So if you chose to change out your Delco plugs for a comprable product from another manufacturer didn't you excercise good judgement assuming you bought the correct Bosch plugs for your car? It's almost like saying when your stock Pirelli's wear down and you go buy some KDW's that the dealer can say your suspension problems were caused by the tires. Just because the aren't stock brand doesn't mean they're not the 'correct' part. Worst case scenario just fix it yourself with junkyard parts. Good luck.

 

I did a search by typing in (Bosch Platinum +4 problems) and got 11 pages of car fourms from Merceades Benz, Porsche, Dodge, Mazda, Toyota, Honda. Etc. Etc. all having the same problem.

Sorry you lost your Warrenty over this your not alone and its not just with Chevrolets.

Go fast goodies are not all they are advertised to be.

 

damn you need to change your plates to UberPwnd

 

Hahaha +1 invisi-rep

 

but seriously, just find a coil pack on ebay and do it yourself. easy fix

 

It was probably a $100 more because of the labour. They never tell you over the phone what the labour charge is.....just how much the part is going to be.

So does this mean that none of the aftermarket plugs are good for the car??
