How would I know if I "popped a few pistons"? My car seems to run fine, and the reason I went to AL 104's is because it was running lean and I was told that could help to keep it running a little colder and keep it from destroying the plugs. Now that I fixed the lean issue, I don't have to worry much about it burning plugs. But that doesn't explain why it keeps ruining spark plugs? I'm not sure what to do since this is my only car and I don't have the money to buy a new one. Hm. Not quite sure what to do here.
