so heres the last update hopefully but still cant figure the idle part out. since i replaced the o2 sensor with a gm genuine one trims are fine even at idle but cant figure out the rpms at idle....

now im seeing fuels going both ways negative in park positive steady speeds lol something has been weird here as i finally had a odd idle and it went into open loop? i cant upload the log some...

even in open loop mpg city is down. was thinking purge valve or behind it but i have it disconnected with the code off and still trims are leanish. i tried to put new gasket and clamp hard to say if...

heres just an update as it is not the purge valve but that exhaust leak. i made a simple tune to disable closed loop and getting the 32mpg that i used to get. but the rpms still move a little at a...

Could just smoke the shop vac and use that lol

I don't have a socket that big lol just a thing that I was hoping that the smoke machine but smoke doesn't work in this exhaust some reason but I'll give it a go sometime.

i got a log here but waveforms look fine but you can see while im in drive/idle trims go up but when i go into park it drops and evens out so it begs the question what is it?

so heres whats weird before turning started the o2 waveforms looks just fine with normal trims so maybe the exhaust leak isnt there? uploaded that log but didnt have the right sensors being watched...

only thing is that the fixkit i have to remove some hoses but still same idea. its just odd that fuel trims only jump up in drive but ill get another purge and see what happens

current logs and tune file. the small one is just at idle

Been trying to figure this out for a while now and all I hear is fuel pump but no symptoms and trims 0 out under load or highway but that was before the tune. I watch long term and it sits about...
