Hey guys I installed Steeda pullies about a month ago and i loved the lil kick they had. Well about a week after that I was on the road just driving normal and I heard a pop under the hood, and then a (no muffler) sound. I pulled over ,checked it out and saw the spark plug thingy was broken. Anyway ,brought it to the shop and paid a couple hundred to have it fixed. He said the plug blew out the hole and stripped it partially. He screwed it back in and replaced the coil and it hasnt been the same since as far as that "extra" pull. Is this because Im losing compression? Any suggestions? Thx.
