shauno Posted May 27, 2004 Share Posted May 27, 2004 It was running awesome until awhile ago it started stumbling or missing at higher RPM's. I used to be able to rev it to 7K with no problems, now it seems to hesitate and I can hear the missing through the external wastegate exit pipe. Almost like bad plugs or something. Has anyone had a similar symtom? My mixture is still in the .83-.85 lambda range and egt's are within limits. My setup: balanced 2.9 with forged internals and heavy cam. Motec controller, 450cc injectors, should be faster... Thanks. Quote Link to comment Share on other sites More sharing options...

Jersey Posted May 27, 2004 Share Posted May 27, 2004 What's the plugs look like after a nice high R run? What's supplying spark? Bad tank of $5/gallon gas? Quote Link to comment Share on other sites More sharing options...

shauno Posted May 27, 2004 Author Share Posted May 27, 2004 Thanks, I'll try to gap them down. But how much should I go? I forgot the stock spec off hand but I'm sure I was at the lowest recomended. Thanks Quote Link to comment Share on other sites More sharing options...
