The CSX: May 28, 2004

I added a little spark to the cal and now the motor is not running well at all. The idle is very rough and it pings a lot.  I backed out the change, but the problems continue.  I then went back to the cal I was running during the winter, but it still didn't help.  I swapped the coil, wires, cap, rotor plugs.  No dice.  Next I decided to look at the timing it looked OK, but when I took off the belt cover, I noticed that the idler side of the belt was very loose.  I figured this was making the timing jump around, but even after fixing it and triple-checking the timing again, it still idles bad, pings in boost, and won't rev past 5k.
