michael5556 247 Posted October 25, 2010 Report Share Posted October 25, 2010 My mk3 vr is developing a random misfire when it's cold outside if I go any more than half throttle, it misfires for about a minute then stops and goes back to running smoothly? It also has a problem with cold starting as the revs drop to around 200 an it either stalls or goes back up to idle speed? I am thinking this could be something to do with oil not getting around fast enough on start up?Any ideas will be appreciated! Link to post Share on other sites
VR6Nat 9 Posted October 25, 2010 Report Share Posted October 25, 2010 could be your coilpack is cracked and when its cold and damp its getting moisture in.... try having a look at it...is it obd 1 or 2? Link to post Share on other sites
michael5556 247 Posted October 25, 2010 Author Report Share Posted October 25, 2010 I am thinking 1 as it is the early one 1992 Link to post Share on other sites

Ben Seabrook 4 Posted November 25, 2010 Report Share Posted November 25, 2010 clean your ISV mate, it's a good starting point on early cars Link to post Share on other sites
