This kind of reminds me of that time I bought those reman injectors from Mylex. They were cheap and I decided to go with them. About 2 weeks later, the engine was running on 7 cylinders and smoking something awful. Had to stop at idi econolines (Rich) place in Sacramento on my way back up to Chico because it was smoking so bad I thought I was going to get pulled over. Long story short, one of the reman injectors completely clogged one of my precups full of rock solid carbon. I went ahead and bought a new set of Delphi BB's after that mishap. I had to use a chisel to break up that coked carbon in the precup. Not fun. Anyways, I learned my lesson there. Sometimes it is better to buy the better stuff for certain applications IMO.
