Erratic idling
« on: August 26, 2011, 19:54:09 PM »
I've just replaced the cylinder head on my Ecotec.
I've only taken it out once so far, but it will not idle normally. It bounces around from about 1800-1200rpm. Before the head was removed & replaced, it used to hover at about 1200rpm before settling down to normal idle speed.

EML is not on but my initial reaction is CTS. Not connected properly or possibly an airlock???

I personally wouldn't of thought either of those would cause erratic idle, I'd say ICV is first port of call....
Lewis Hamilton said that winning his first race felt better than having sex. Kimi's reply to that was, Maybe he never had sex.

My first check would be the Idle control valve.
