hi there
I do have a E53 4.6is and and w/ engine at idle in parking ,everytime I step on gas pedal up to 2-3000/rpm and then let the engine come back to idle speed (6-700 rpm or whatever)....it goes under to much almost to die for one second and then it comes back to normal ,it doesnt come back from higher rpm back to 6-700rpm smoth like it should.For those who know the tech of this engine M62 could u tell me who controls this rev , I do have a new EDK ,new spark plugs, new ign coils .THANK YOU
