wtf ... ?
I ran it some, enough to heat up the gaskets and water, for a little while. I was also enjoying the open header sound for a little bit, take off to drive and now it's missing like a SOB!
Any ideas ?
I haven't checked the wires yet, it seems like it's mostly bank2 being 2, 4, and 6 mainly with an occasional 8. The other side isn't worth mentioning.

Did you pull the plugs during the install? I bumped my plugs when I put my headers on my previous truck and had a bunch of misfires and blinking SES lights because of it. I replaced all the plugs and had no problems after that.

I didn't pull the plugs out, but I did pull the wires off. I'm going to the parts store tomorrow to pick up another set of NGK TR55's.
I don't wanna replace wires yet, but if I have to, it's going to wait until I get some Taylor wires in or something.
Still no rain here either ..
I cross-threaded a header bolt when I did the install too. It was a major PITa to get it in. it was the one in the very back on driver's side. After getting it half way in with a wrench I could finally get a socket on it and get all of 2 clicks at a time.
I may be putting heads on here sooner than I wanted to ...

seems like you need the 02's 12" from the opening, i am not sure of that info so maybe someone else will chime in, you can put a dump right where the cat's are but i would put an extention on the dump or do whatever you have to to get far enuff away. i only drove the truck about 10 miles and the first couple were fine then it started missing, i think it went way rich but i am not sure

yea i heard like you needed like atleast 8" added on past the 02's.
but like parish i am not sure. i drove mine and it missed but it was cause the comp heeded tunning realy bed. you could not even get half throttle.
