|
|
Having just purchased a 2003 V6 Delica and giving it a good once over, there is a curious problem with the idle speed. On cold start up, it idles fine, around 700-800 rpm. once fully warmed up the idle speed increases to around 1500 rpm. it has an LPG conversion (Prins system) and idles at 1500 regardless of any fuel. I've cleared the two fault codes (MAF and intake temperature) but still the same issue.
Any ideas? |

Prins is described to me as a "follower system", and should take its instructions from the Mitzubishi engine ECU. You may well know all this.
You have said that the higher idle speed continues with either fuel system (gas or petrol). So, presumably you are knocking off the Prins system at the dash button and running petrol even after gas temperatures have been reached and swtiched over automatically? Are you sure that the dash button is giving you the setting correctly?
My suggestion would be to take the vehicle to a Prins Certified installer, where they can very easily check how things are running by hooking up to their computer system. |
