Asked by Peter Luthaus
I own a VS II Holden Acclaim wagon. For 30 to 40 seconds at the beginning of the first start of the day, the engine idles very roughly, almost to the point of stopping, then it picks up and runs smoothly. All subsequent engine starts after that are fine, with the engine firing almost immediately and running smoothly. The engine runs very smoothly, both on and off the highway.

25 Sep 2003We contacted Holden for their response, which is: ``While it is impossible to diagnose a car without sighting it, rough running on start-up and/or hard starting can be caused by many things, including leaking injectors, carbon build-up on the valves, etc. Injectors wear over time and are also subject to deposits from the fuel. Given the age of the vehicle, injector leakage is a possibility. This is not a generic V6 problem. If the injectors are in fact leaking, this is a maintenance item. Injector leakage can be tested by carrying out a pressure test and confirming pressure drop.'' I think this is good advice. Take the car to a fuel-injection specialist and have them check the injectors, and think about having them cleaned.
