Hey guys so car sat for 1.5 - 2 mo or so. Drove car around and made a pull. Everything was fine so i went about my business driving around. Come to a stop light and car starts idling 1500 rpm. Some times it would drop down a bit but go back to idling there. Go home, did boost leak test and all was good. Changed omni 4 bar for new one just to see. Went back out for a drive and kept doing same thing but this time it started returning to normal. Now it would idle normal but much richer around 13.1 - 13.8. I tried to pull fuel out on the sd rpm table and upon startup it seemed to work and went right back to idling rich. Car is an evo 8 on sd, gsc s2 cams, and running full time open loop. What do you guys think? I was thinking leaky injector or something? idk. Any suggestions and ideas would be great. Thx.
