Header install problem
Hey guys. I just in stalled longtubes on my car. Codes came up and I accidentally reset the codes and now the engine is hesitating, surging, and bucking while driving. I'm like stepping on the gas and the car isn't going anywhere and all of a sudden it jumps. Either that or I'm stepping on the gas and it hesitates badly and I'd have to restart the car. I'm scheduled to get a tune in April because my tuner is book till then.

Check your front O2 sensors and make sure they plug in on the same side they are installed, i.e., fronts don't cross. Also, check all the engine grounds if they were removed. Then check your plugs if you left them in during installation, they are easily cracked.

as stated above, check codes again and make sure the O2 sensors didnt get swapped and plugged in to the wrong location, common mistake is to plug the front sensors into the rear and vise versa (on the harness along frame rail). also make sure you O2 sensor wires didnt lean against the header and melt.
Did you replace plugs and wires during the install? any way to scan the car? I would suggest New Irridium plugs and GMPP wires. should show up as a missfire but might not trip a code..
