160VVC - Starting issue and a few others...
I've got a 160 VVC out of an Elise in my K3, and I've got a few slightly odd problems (or features?) I'll list them all as they might be related...
1) Over the past week or so, when cold, the car sometimes will start, run for a second then die, but will
always start fine on second attempt after removing the key and waiting 10 seconds.
2) 5500rpm rev limit - I have checked all plugs and they are in the correct place, VVC mech is just about movable with the HCU off.
3) Occasionally a erratic idle - although this hasn't happened for a while, and not since the starting issue has developed.
4) Slight off power backfire at low rpm - nothing too loud, just a cough or two on deceleration (might be a feature?)
The car is currently without a Catalytic converter - planning on putting on on as marginal on noise and have heard the VVC benefits from a bit of back pressure? As for whether sensors are working - who knows, there isn't an OBD plug and I haven't been able to find out how to wire one in.
Any clues on how to approach sorting these? I'm fine with pretty much all mechanicals but not overly clued up on engines.
