So I replaced all my plugs an coils a couple of weeks ago because I was getting a misfire. So after doing all the coils and plugs it ran 100% better then after about a week it started happening again and in that time I had got a tuner so I read the code an it was cylinder 7 so I put another new plug in to see if that would fix it. But it did not. So them I got another coil an put it in and it fixed it for about 2 days and now once again I have a cylinder 7 misfire. The first time I did the change I used plenty of dielectric grease but when I put the 2 new coil in cylinder 7 I didn't have any left. So I bought some more and I'm going to fill the coil up with it later today and see if it fixes it. But I don't think that it will because the coil I still in contact with the plug an the grease is just there for longevity. But what I don't understand is why it worked for 2 days and now it is messed up again. Does anyone know what could be wrong?

 

I had this problem and I was getting a little antifreeze in the hole for the plug/cop. After I got the leak fixed it quit burning up cops

 

What cylinder was it? I heard the antifreeze leaks on the passenger side near the back. 7 is on the drivers side.

 

But I could be wrong. There is a little bowl type thing right over cylinder 7 that makes it a pain to get off. Does anyone know what this bowl type thing is?

 

are u sure the threads arnt screwed up and the plug keeps coming loose? my truck was missing on and off for months and finally i replaced the coil in cylinder 3 and it fixed it. or so i thought. when i replaced the coil it just shoved the plug back down. that was a week ago. yesterday the plug in cylinder 3 blew. it was the plug all along and once the threads are messed up it must be fixed. just thought id throw that out there just incase lol

 

I put a new plug in earlier and when I took the week old plug out it was still at 28 ft lbs. something has to be shorting out the coil. It has to be this bowl above it. I had one of my plugs on the other side shoot and I fixed it with one of those inserts and a different coil boot and an odd plug.

 

The little bowl thing is connected to the fuel rail with a plug coming off of it. Is it possible that this is leaking?

 

I think its some kinda regulator on the fuel
Put something around it and drive around or let idle for a bit. Remove it and see if there's any moisture

 

Will do I will tape a little cup under it or something and see if there is any gas or something in the cup. If the coil did get wet does it ruin it? Because I'm tired of buying new coils lol. Can I just dry it out and fill it with dielectric grease again?

 

It burned all mine up that I used while I had the coolant leak
