Too much idle airflow Hi,
I've recently put a Harrop Hurrican ITB intake manifold on my LS3 and find I am getting too much idle airflow. Has anyone else had a similar issue to this (not necessarily with an ITB intake) and how did you get around it?
The motor is basically a stock LS3 with a 227/243 comp cam.
It will idle at around 900rpm, however this is with the IAC fully closed and around 0-5 degrees timing, so not ideal at all. This means the revs will hang a fair bit when coming to a stop unless I pull a heap of timing from the main timing table also. Not sure how I'm going to get around this issue.
Cheers
Benno
