What are somethings that would cause this? I just recently switched to long tubes and duals and never had these problems before. I also blocked off my EGR and AIR when I installed the long tubes. Could this have anything to do with it and is it possible I may need a good tune for the new exhaust and air/egr block offs?

Anyone?

Did you turn off the EGR in the PCM?

you could have burned a wire on one of the long tubes

even w/ heat shields, they can't touch at all. need air gap all around

Im really not sure. Its been so long since I got the pcmforless tune I dont remember. If not, could that be the problem and what would it do?

Wouldnt a wire be a constant miss though and not intermittant?

i burned a wire once and it stumbled at lower rpm.
above 3,000 it got less, but yeah, dint go away entirely

Mines kinda weird cause it doesnt happen all the time or everyday for that matter. I looked through the plug wires and didnt see anything but maybe I could tell more if I had it on a lift.
