Well, my 2003 Vectra 1.8 sri dual fuel has been running rough recently, but only from start up when cold and within a minute it's running fine. Today the engine management light came on and is reporting fault codes 2103, 0170, and 0565.
It runs on petrol on start up, and after a minute or so runs well, and then switches to LPG as normal. It runs fine in both petrol and LPG mode. The problem only occurs when the engine is stone cold in any outside temperature.
Could anyone shed any light?
I don't think my engine has an EGR?
Could it be a MAF sensor problem?
Thanks guys, and as always, any advice appreciated.
