Guest Matthew123 Posted March 13, 2007 Share Posted March 13, 2007 I have a recent rebuilt L28 turbo. It's running MSnS 029v and everthing is stock except for a msa cam. I'm using a fuel map that i know to be good, but it is running so rich it will not idle. It has no vaccum leaks, but it has almost no vaccum. Everything checks out good that i know of. What would cause this? Thanks Quote Link to comment Share on other sites More sharing options...

HB280ZT Posted March 14, 2007 Share Posted March 14, 2007 I would start with timing also. Use a timing light to verify that you have the same timing on the crank as you have set in the MS at idle. If it is the same then check the initial settings and try to get the kpa down to around mid 30's or so. Also your fuel map could be way rich. I am running about 8.3 on initial and mid 30's on map and I am running at about 14.5 or so on my LC1 at idle. Also remember that you will have to let the car warm up if you have an enrichment setup for cold starts. Just some things to check.
