Captiva has a 2.4 engine, first off the car seams to run fine when cold but once it warms up it runs ruff , when I checked fuel pressure it is at 43 psi I didn't think this was enough pressure so I put a used pump in the tank this car also has a high pressure fuel pump on the engine . I'm attaching a couple pictures of the data I got and also a graft of 02 sensors. Any help would be appreciated. Thanks
