Well, after some time researching how easy/nooby a spark plug replacement job is, I figured I would jump in and try to replace my own since I just bought my car, it's almost at 30k miles, and I want the experience.
Well, I heard the most spark plugs are pre-gapped, and the SP-532 are advertised as such, so I didn't bother gapping when I tried it the first time (had heard of gapping previously).
Well, the engine rumbled and shook when any amount of boost applied and idle was rough, so took them out and the porcelain was cracked on all of them and broken on one.
So, I attempted a couple more times with different gaps. Tried .025, .028, and .030 again (OEM gap).
.025 and .028 were both wrong as there was still some misfire under boost, with .030 being VERY rough like first time and causing porcelain breakage once again.
I just want my car back. I scheduled a service on thursday, gonna deal without a car for now I suppose.
I know that spark plugs are supposed to be torqued, but I've talked to several friends that have done spark plug changes and none of them use a torque wrench, just tighten it until you cant anymore with your normal wrench.
Has anyone else ran into this before? Or heard of anyone not being able to get spark plugs right?
