hi folks, new member here.. just bought my self another w210 e55 amg, after selling my bmw 635csi - now the car had been locked away in previous owners lockup (he's in spain most of time). Battery was completely and utterly dead, and the guy who fired it up for me had jump started it. it was laboring like a sick pig - so i told him to charge battery fully and id come back - back 3 days later, fired her up and purring like a kitten - now i never really shoed the car until i got her home to be inspected by mechanic first, but once he checked oils etc. i took her out for the obligatory blast - now unfortunately, blasting is impossible, when it is shoed into kick down, it doesn't kick down, it hesitates severely, sort of at about 4 thousand revs, and jumps back and forward - drives completely normally if i drive it like im going to bingo, but lets face it how much use is that? my question is would the long term of the battery being flat cause some sort of loss of throttle memory or something? also when you rev the car and its sitting stationary, it also limts out at 4000 revs? any help would be fantastic... thank you in advance guys..
