Hey everyone I recently bought a 2004 y61 4.8l with roughly 123km on the clock. The guy I got it off told me about the issue but I thought I'd take a risk and buy it anyway. Occasionally it will lack power and when it does this if you touch the throttle it just wants to stall. I have replaced the fuel filter and no success. I can hear the fuel pump working fine. It has a new throttle body + MAF sensor. New spark plugs also. It really has me stumped, Im kind of leaning towards 02 sensors but not 100% sure. Any help would be much appreciated!!
