Okay, I am suffering with a 2010 Chevrolet Equinox with the "legendary " Ecotec 4 cyl. Lol. Back in January my Stabilitrac light came on. Mechanic replaced the right front wheel bearing saying that was the problem. Amongst other things that he did for my vehicle inspection ( all 4 brake pads, rotors and calipers, tires, oil change and exhaust) he cleared the codes and passed the vehicle. While I was topping off the oil ( which I do FREQUENTLY 2-3 Quarts a week, I drive @500 miles a week [no leaks]),

I noticed that the tube for the PCV that connects with the intake plenum was missing. I found it tucked away under the plastic shield for the valve cover. I re-connected it, and as soon as I started to drive it, it shut off every time I came to a stop, the stabilitrac light came on, the info center notified me that the engine power was cut down to 50%, and service the stabilitrac. After trying to restart and drive several times, I disconnected it, re-tucked it back under the plastic cover and now it runs fine. So, my question is what does the PCV tube have to do with the stabilitrac? Here is a picture. P.S. I am contemplating running a vehicle built before 1973 from now on, lol. Thank you.

Thank you for your reply, unfortunately it was a nice bright sunny day. I have tried to re attach the pcv valve tube again the next day, and once again it acted up. I am going to replace the pcv valve, clean up the baffles in the engine and replace the spark plugs while I am in there.

You just have a clogged pcv building up oil pressure and it's cutting the power so it doesn't blow seals it's a safety device the stabiltrac light came on cus that's what traction control does

engine is a crapper, all worn out. removing the pcv valve adds extra air so the engine can run. Get rid of that piece of crap soon
