I'm up in Austin considering my options with my '99 EX. Your old sporty in your cardomain was awesome.

I don't suppose you know where that truck is now?

Just discovered on mine that the exhaust mani was cracked (probably because the exhaust pipe hanger below rusted away), and the gasket leaking at the ends. I'm guessing the crack and bad gasket let in illegal air, tricking the O2 sensor into thinking the exhaust is lean.
