07 xc70 and there is no responce from the engine until I depress the gas pedal about 1/8". Have had 4 other volvos with this 2.5lpt and the only one that experienced a delay like this was my 2003 xc70. Hate to take it to the dealer. Might resetting the ecm resolve this. I have no problem pulling the fuse(s) but shouldn't I go through some sort of learning/startup procedure and what is it.
