twodogs Posted November 25, 2019 Share Posted November 25, 2019 Hi guys, I've got a cold start issue. It's an Fgx Xr6 na which is completely stock apart from 2.5 cat back. When it cold starts it revs to about 2000 / 2200 rpm for about 5 seconds , not good for a cold engine. I had an earlier model Barra done the same and it only lasted 70000ks... Is there any way of curing this with a tune? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 25, 2019 Share Posted November 25, 2019 You probably have an air leak. I bet your idle timing is quite low indicating the idle feedback control is fighting an air leak. Quote Link to comment Share on other sites More sharing options...
