I just put full exaust on my car and deleted all the codes, exept the egr stays on no matter what. The car runs horribly, it backfires at low rpm when under a load (over drive going from 50-70) and when u whack it it stumbles like cccccrazy. it didnt do what when i first installed it but i think its cuz i never really opened it up.

what do you mean you deleted the codes but the egr keeps popping,did you just clear the codes or permanently tune them out?

Could very well be you have your 02 sensors crossed, check them out. Also a common thing would be exhaust leaks close to the 02 sensors.

i deleted them i didnt tune them out, but they dont pop up for a while when i just delete them. I think its because my 02 sims are telling the computer everything is ok when its not, but that exaust leak is a very good though becaust it does leak between the header and Y pipe, i bought the heavy duty clamps but i need to get the car way up to bend them around the pipe and clamp em together again

First, make sure that all of the spark plug wires are fully seated on the spark plugs. Did you remove the spark plugs during the LT install? If not, I would remove each spark plug and make sure that they are not cracked.

i actually just did check the front plug, it looks like its runin a little hot. Im gunna go over the boots again to be sure, but i figured if a boot was off it would throw a code sayin so.

you don't have sims hooked up to your front O2s do you? Ther eis no need for sims if you have the back O2s removed and their DTCs wiped out...
