A bad front 02 will cause it to run bad - what was the code?

I had that problem after I installed my headers. I chose to not remove the plugs thinking I would be careful around them. Turns out I cracked a couple so I replaced all the plugs. It still ran like crap. Replaced the wires and ran like a champ.

I'd get theose o2's replaced and then change the wires. I went with MSD's

do the 02 sensor first, wires can last hundreds of thousands of miles before they *need* to be replaced
