This is getting worse and worse, just went out today and 15-20% throttle position is almost max on the engine. It will feel hesitant/laggy when keeping it constant then just a bit extra on the pedal and it jumps. Also the cars been going into to limp mode recently. It does get up near the redline alright just feels like its struggling most of the time. Could it be wiring or ecu related? Or something fuel/ignition?
