Like 150k on the car, so I'm actually pretty impressed that these are the only problems we're having. Those electric fans just seem to suck in this generation Mustang. It might be worth putting a Perma-Cool in and just hardwiring it on. Damn Ford electronics.

From what I've read, the WOT ping is carbon buildup in the heads. We timed the car back to 10 degree manufacturer spec and adjusted the TPS to be almost exactly .98 volts at idle. It still knocked a little, but with the addition of new ignition stuff it basically went away. We tipped the timing up to 14 degrees to give the throttle some grunt, but still just a slight knock. I'm gonna run steam through the engine next weekend to see if we can break down some of that carbon buildup.

Worst case scenario, we pull the motor and rebuild it. It's got 150k on it and it's a bone stock 302. That car could use a little buildup anyway. An aluminum head 347 sounds like a much better engine to be under the hood if you ask me.
