Checked all grounds and were all fine, also swapped out MAF and another set of injectors with no change but I did install a set of splitfire coils that made a huge difference, car runs better with them than it ever has even with a larger spark plug gap but the gauge still reads lean, can't hear the car spark knocking and plugs look good after a WOT pull so thinking my lean condition is either a faulty wideband sensor from being run super rich and like crap for so long or has to be recalibrated, do the aem uego need to be recalibrated? If not a new sensor will be my next move
