Hey guys

I'm new to the site and need some help .. I have a 06 hummer h3 3.5 that's been nothing but issues .. First at idle it would run rough , I replaced the mass air flow , OEM plugs , cam shaft solenoid , intake solenoid , variable camshaft solenoid , New battery terminals ,Intake tightened with new gasket , throttle body cleaned .. Was better for a bit , but one night I noticed when I gave it gas it kinda sputtered , Lots of oil comes out the PVC hose connected to the valve cover. Now it starts up fine ,still a but rough , stability control light is on , traction control too .once I start driving it has no power at all , I imagine this is limp mode .. I've read so much stuff on line and can't figure it out ..Any help would be very much appreciated.. Thanks

 

could be blow by from worn engine or sticking valves. but if it gets worse as you rev your cats might be clogged. you can remove the oxygen sensor and if you feel a lot of pressure coming out the hole and the revs are better then i guess you found the issue. you should have maybe 2 psi at the bung

 

Year, Model, Miles and history of recent work done just before any symptoms started.

What kind of "new battery terminals?" Junk auto store cheapies, or a quality aftermarket set?

Acts like it wants to stall/rough idle -No CEL -What To Do:
