Scooby Posted October 8, 2006 Share Posted October 8, 2006 I finnished fitting my Apexi boost controller last week and was having a spirtited drive along my private road last night with my mate in his Z3M coupe. It was then I noticed in 3rd gear at about 5500rpm on full boost (1.2bar) it started to missfire very slightly, I couldnt feel the power dropping off but I could hear it missing. I am still running standard plugs and they havnt been changed in over 18 months, could this cause it or am I looking at a fueling problem?? Remember I am runing full UK TT setup.

Thorin Posted October 8, 2006 Share Posted October 8, 2006 This should help... http://www.mkivsupra.net/vbb/showthread.php?t=41927 IK24's recommended. Check your coil pack connectors when you replace them as they can be a bit brittle now. Quote Link to comment Share on other sites More sharing options...
