Hi all. I've been racking my brain over this weird problem I'm having with this car I tuned last week. Vehicle info: 2000 Oldsmobile Alero 2.4L, auto trans, with a turbo kit the owner pieced together. I tuned it on our DynoJet last week and everything seemed fine while it was on there. When I took it off and tried to go on a test drive it cut out a second into accelerating. It doesn't totally die though; it goes lean, engine cuts for a second, comes back for a second (richens up), dies again, comes back... You get the idea, foot on the throttle the whole time. It acts like it's cutting fuel or ignition, but it's not showing on the logs. I've tried turning off closed loop, torque management, any limiters, and it still does it. Has anyone ever come across something like this?
I attached a couple logs of it doing it. You can see it doing it when the O2 goes lean when on the gas.
Thanks for any help!
