So I have been working on this car for almost two weeks now, noticing this and fixing that. I have unfortunately gotten to the point where I am stumped and don't know what else to do to even get the car to idle properly. There seems to be a lot of lazy issues I have discovered with the car, for example the IAT sensor was broken in half and whoever previously owned it just created plugs to attach to what was left of the sensor, or that the MAP sensor vacuum hose was attached to something that had nothing to do with the manifold. I will post a couple logs, its even to the point my front O2 sensor no longer cycles, not like it ran well even when it did. Any help would be appreciated, I'm kind of at the point I don't even know where to begin. I will post a few other things I have done/noticed since I got the car below.
So I tried running a boost leak test, I do hear the air coming from the oil cap opening, other than that only small leaks at the throttle body that should have already been fixed. Going the other direction, only leak I could hear was at the bov piston. I rewired the MAP, Wideband, and IAT sensors following posts on here, still do not trust the WB readings, it seems like its acting funky. I've fixed a couple vacuum hoses not routed properly, I think I'm going to get an ethanol tester or drain the tank and start over at this point. It doesn't run consistently and this past time didn't even move to closed loop. Yesterday, it would bump into closed loop then the fuel trim would shoot up to 20%. Also, can't get the AirFlowPerRev down, but its already 75% down from what it was before the MAP vacuum hose fix, which also reduced the airflow. I just feel stuck. Please ask any questions and I will promptly respond and or take photos if needed. Again I appreciate any help.
