well i said i think its more responsive but not sure as i dont have it on the road yet as just getting it ready for mot. so i just wanted to know what will have been happening if it was left unconnected. is it flat .would it be worse on mpg. will it run uneven ect . basically would it run poor. as like i say have not driven it yet on road as only just purchased it so i wouldent really know what it was like b4 i reconnected it. other wise i wouldent be asking the question

strangely mine runs better disconnected. If I connect then putting the gear selector (auto) into D etc, drops the revs to nearly 300 and it rumbles away till either stalls or revs up to 2000 then steps down, if I put it in N before stalling.
