Took a 20 mile ride to make the engine 'learn' the current characteristics after polling each component. Disconnected the battery, let the codes get reset. At Autozone, the issue was diagnosed as a Mass Air Flow sensor issue. Now registration renewal requires the vehicle to clear the emissions test. While in the USA, close to the vehicle registration renewal date, my Check Engine light came on. The Cleaner also distinguishes itself by means of a very fast evaporation that is free of residues. I can relate to this one!!! Folks in the USA can try this out in case they face this problem. My Skoda has a gained a little torque and less stuttery during a cold start. Restart car -don't expect wonders until 10km later once the ECU realises that the MAF is hopefully more effective. Remove sensor and let it stand till most of the alcohol evaporates.
