Strange Rough Idle on Starting
Posted: Thu Oct 31, 2013 2:11 am
This seems to be a bit of a weird issue.... On startup from cold I seem to be getting issues, on occasion the starter seems to stay engaged and on other occasions it will start gets upto around 1000 rpm and then drops off and stalls.
All of this seems to be avoided if I give it a little gas.
I have done a lot of searching and see a lot of posts relating to valvetronic levers? I am guessing this is what it maybe but is there anyway of nailing it down to this? I have no warning lights at all.
I have recently replaced an ignition coil but not sure this would have any impact as this was causing a misfire whilst driving at any speed.
Any help or previous experiences would be appreciated.
