Default After header install having problems

Put my LTs on a week ago, car ran fine for the week and as Im driving the day before yesterday the SES light started blinking and the car started to slug. Pull over to the side on the road give the car a quick over look eveything looked fine. Get it to the house look over it again find nothing. Next day start it up drive it around, ran fine all day. Today started up fine, as soon as I go to get on the highway started to lug again. Now it only does this on acceleration, crusing its fine. Any insights?

probably burnt out an o2....LTs will tend to do this alot, also check your wires and make sure none are near the headers

Definitely check the wires that run by the headers. A buddy melted a few of these and the car was running like crap and showing codes, etc.

If it is the wires, if they are damaged, obviously repair. If not, just make sure to move them as far away from the header and get some heat shield tape, etc. on them for added protection.

Did you pull the code on it? Get it scanned and see what the code set is and I'll help you out.

I had the same problem atfer my install. If the wires are good you probably cracked one of the plugs. Scan it and see if it gives you a cylinder that is misfiring. It might just give you a random misfire code also. That means you have to pull them all. Just my 02 cents.

Make sure #6 isn't arcing on the header, and 02 wiring is fine. Wouldn't hurt to check the ENG SEN fuse either.
