was this something that just started did you make any changes to the car first thing also if you were under the hood check for vacuum leaks sometimes we break hoses or loosen them while were doing something else where are your blms at also check for exhaust leaks cracked header check at the 3and 5 tubes . check the hoses at vacuum block .check all your grounds battery connections these are the most commend and easy stuff to check first before going to the cam sensor or coiland module and also when was the last time you changed the plugs wires.

I noticed you had E3 plugs in the car you sold. Do you also have them in the car that is sputtering?

put a wideband on the car and see where the tune is at,guessing can be costly and chasing your tail replacing parts is no fun and can expensive quick.

Haven't had time to investigate further. This just started basically the 2nd time I have taken it out since I bought it. I don't have E3 plugs in this car that was in the old GN.

 

[turbobully]

No idea on plugs and wires I guess I should start there anyway since I don't know how old they are.

I am familiar with Vortex I just combed through the site I didn't find any info on the coil pack.
