mattp1983 0 Posted February 14, 2009 Report Share Posted February 14, 2009 My MK2 VR6 conversion cuts out about 10-20secs after firing up....It seems to be over fueling, and just before it dies it starts to miss fire slightly.I have changed:MAFCoolant Temp sensor is brand newNew plugsSwapped Relay 109 with a known working one out of my mk4.Vag com shows nothing.It is decatted with boss for lambda probe.Any ideas? Its a coil pack engine. Link to post Share on other sites
jellsta 0 Posted February 15, 2009 Report Share Posted February 15, 2009 could be the coil pack mate, try one from a known working car if you know anyone with a vr6 first though before you shell out for one.. Link to post Share on other sites
mattp1983 0 Posted February 15, 2009 Author Report Share Posted February 15, 2009 I'll take it off and inspect it, thanks mate. Engine was stored in a bodyshop for a couple of years and everything was full of dust, had to replace a fair few ancillary parts. Guess the clicking I'm hearing could be something arcing out, thought it was chains at first but its intermittant and engine has only done 60k.Would the plug leads possibly cause this? I havnt changed those.... Link to post Share on other sites
mattp1983 0 Posted February 16, 2009 Author Report Share Posted February 16, 2009 Coilpack seems fine, so have ruled that out....... Link to post Share on other sites
