Hello all,

My car seems as it is detuning itself from time to time.

In the Morning, the car runs normally and after about 15 minutes of driving, it feels sluggish.

I also have the CEL come on every so often, but when I pull codes, it gives me an 05 05.

I just changed the front 3 spark plugs and need to get the rear 3.

My Car is supercharged by the way running standard pulleys.

I am guessing it may be the knock sensor but I get no ghost codes for it, MAF, or coilpacks?

Any help is greatly appreciated.
