Guest slepts13 Posted March 4, 2008 Share Posted March 4, 2008 My buddy and I just got this car running today. Now it acts like it is missing and is getting backfire backinto the intake. We can seem to get the idle to stay still any insight would be awesome. Thanks Quote Link to comment Share on other sites More sharing options...

HowlerMonkey Posted March 30, 2009 Share Posted March 30, 2009 Is the distributor and cap and rotor new? I've seen carbon tracking do some really wierd stuff. Quote Link to comment Share on other sites More sharing options...
thrustnut Posted March 30, 2009 Share Posted March 30, 2009 No idle and backfiring into the intake sounds like a vacuum leak, just went through this on my build. Quote Link to comment Share on other sites More sharing options...
