Default Getting P0300 code after LT install, please help!

Two days after installing my Pacesetter LT's My rpm's have been fluctuating at idle and during acceleration here and there, so i scanned it with the OBD II and getting (P0300 Random/Multiple Cylinder Misfire)
The only thing i can think of is stock ignition wires might be getting too hot near the headers, as the passenger A.I.R. extension touches one of my wires, but im not sure if that might be the problem
If anybody has any knowledgeable input it would be greatly appreciated, Thanxs guys

Maybe one of you plug wires is loose? I would go back and check the plugs and wires.

No, that the first thing I checked to see if all the coils where pushed in all the way, especially the back passenger side which is a bitch to get to, I,m just wondering if anybody ever had the same problem

did you bang into or crack a plug when you were putting the headers on? or did you have the plugs out when you put the headers on?
