P0300 at low rpm?
Any clues?
Few things stand out... fuel trim difference between banks. Also engine load and manifold pressure not high. Seems happen on a trailing throttle and not at wot.
I was running the aquamist on both occasions and will run the car with it off for a while now and see how it goes.
PS... seems I have a crack deloping on my crank pulley
Besides all this car runs incredibly strong.....

MAP will be low because your RPMs are 1800 and S/C is not engaged.
If you are running methanol / water this can cause the fuel trims to be off.
Keep in mind that in our cars the more parameters you choose the monitor the slower the sampling rate becomes.
