Help please! I have A4 2.8 Quattro that is vibrating terribly in Park and Neutral, EPC light is on and the car will only accelerate after constant throttling, since the car is "safe mode" now the abs system is disengaged I can't really drive it, I changed the MAFS and the engine speed sensor and no luck, took off the cam position sensors one by one and still no difference, the CEL was already on and the last code it threw was regarding a possible small EVAP leak, bad fuel cap(I had to replace it with an off brand cap previously)....I know this sounds like a host of things going on, but does anyone have any clues as to what's going on here??
