aman00123 Posted July 18, 2010 Share Posted July 18, 2010 Hi, I have a slight issue on idle if anyone could help. Basically it misfires on idle and when I first start it up the revs drop quite low and then start going between 500 and 700 before it settles down after a few minutes at around 1000 revs. I have had the car looked at and couldn't quite see what the issue was, plugs have been changed, coil pack connectors have been tested by checking with new ones aswell..... The ECU is stock before anyone asks, car is BPU running at 1.2 bar, does the same thing running at stock boost too. Any help would be appreciated Aman Quote Link to comment Share on other sites More sharing options...

aman00123 Posted July 19, 2010 Author Share Posted July 19, 2010 Don't think theres a vac leak, I'll clean up the ICV when I get it back but didnt think that would cause a misfire Quote Link to comment Share on other sites More sharing options...
absz Posted July 19, 2010 Share Posted July 19, 2010 If its only on cold start up then it maybe the coolant sensor, if its all the time then it can be a vac leak check the pipes around the map sensor and fuel regulator. low revs 500/700rpm may seem like a misfire as its very lumpy.
