So, I was getting a primary A coil error. I changed all the spark plugs and I bought two ignition coils and I installed the first two cylinders first. Then I drove the car for a few days to make sure these ignition coils were legit. Which, I bought from eBay. So I decided to buy two more ignition coils from the same seller. I just received the two today. I installed them and my car's engine light came on. When I used my scanner it said primary c, and d coils are messed up. But then I started to notice that the ignition coil 4 was super hot and started to smoke. So I turned the car off and took out the new ignition coil that I just installed and put in the old ignition coil. I hooked up everything and I started the car and it started much better. But, I didn't get any smoke at all and the ignition coil wasn't hot. Then after that, I ran my scanner again and I was having trouble with coil 3, which was the other new coil I installed. I got miss fire for coil c, So I took that newly installed coil and I put the old one back and then the light was gone! After this, I emailed eBay and the seller will be sending me two brand new replacements. Coil 4 did burn up and melt. I want to know if I did anything wrong or was it just my luck that the coils were bad and it is good that I am getting a replacement. Also after I put in the two old coils, please note, I test drove it after this, and I have two new ignition coils, in cylinder 1 and 2, and the old ones in 3 and 4. The car is running great. I just don't want to mess up the other two coils when I get the new replacement. I am kind of worried I did something wrong! I will be attaching photos of the coils. Please help!!! I hope I get feedback before Saturday, which is when I will receive the replacement. I also attached what dielectric grease I am using! I attached the coils pictures below! Someone please help me! I hope I didn't do something wrong and I just had bad luck with a bad batch!

I understand that, but I also should you the exact model number and the coil. They are exactly what is sold from Toyota! I saw pictures of both!

I don't care about the box, I care about the model on the actual coil. or is that the wrong way to know?

Here is the other things. it is completely possible to get bad parts sometimes. It does happen right?

The first two I bought worked perfectly fine! The seller is sending me brand news ones and its already shipped and he did mention that he buys directly from denso!

Here is my question. if the first two I bought they didn't behave like that at all and the car is running great. So, after that I decided to buy two more. It wasn't like I bought from a different seller.

One had two rubber gaskets and I had to push it down and it might of not set right in cylinder 3, and I just remembered this because normally they only have one rubber gasket! So now I am wondering if that could be a problem! That could have caused cylinder 4 to burn out and 3 to get messed up, I am referring to the ignition coils when I say that!
