I need some serious help here :bawl: . I just jot done installing my TOG Headers last Fri Night and having some problems now. After the install I removed my rear 02 sensors and my stock y-pipe in order to drive it to the shop the next day. IN the front the put the front O2's back it the headers and drove it staight headers for a few miles the same night and the next day to the shop. While doing this the service engine light came on also. At the shop they had to weld directly to the headers the front 02's in to get the y-pipe to fit right to the opening on them They also put the rear 02 senors back in. So now after all the my truck is throwing these codes off. The truck is missing during idle and driving around town along with that it is back firling a little. Power now is very stick very little power at throttle. By welding on the headers or driving with open headers with front 02's in are the front 02' gone or the rear ones. I have check my plug wires like 5 times to check the connection which seem to be on good. If anyone could help me here I would be grateful to them :worship: .

Thanks and please help.
