Cnote0ne Posted April 22, 2022 Report Share Posted April 22, 2022 My 350z has a hot start up issue. After driving for a few miles and I let it sit for 30 minutes it will not stay idle. Any help would be appreciated. Please see the attached log. Thanks. Log 2022-04-21 8;50;14 pm.zip Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 22, 2022 Report Share Posted April 22, 2022 Its a bit hard to tell with no lambda, but if I were to hazard a guess I would say "heat soak" of the IAT sensor and metal around it causing it to run lean after a hot restart until the temperatures start to equalize. You could try adding some extra fuel in the IAT trim table for the first minute or so of running when IAT is high. Quote Link to comment Share on other sites More sharing options...

I turned it on and so far it seem to work. I'll adjust the table if it need it. Thanks. Quote Link to comment Share on other sites More sharing options...
Cnote0ne Posted April 22, 2022 Author Report Share Posted April 22, 2022 I have another issue with a code 73 that keeps popping up. I was told by Link Support to change the throttle relay but that didn't fix it. It happens randomly. I can't seem to load the log, only 43kB allowed.
