Hey guys. Just got my evo back from the tuner and drove to Cali from Utah. It seems that I have a lean idle problem. This problem was present before I brought it to my Tuner. But when I picked it up it seemed fine. About halfway into Nevada I noticed the issue was back. Very reputable tuner and i trust him. I just think there is a mechanical issue. He boost leak tested it multiple times and it came back good. I was wondering what else it could possible be? It's running at about 15-17 on the AFR right now. Only at idle. I am going to go through the intake and replaced all the gaskets and vacuum lines in a few days. Not sure if that will do anything besides give me peace of mind. Little background on the car. Its got BC 272 cams with springs and retainers, 1200cc injectors (scaled properly I assume, runs perfect except at idle.), walbro 255 fuel pump, stock turbo. Also my mechanical knowledge is not the best. Any help is appreciated, thanks!
