So I have 217,000 miles on my Terrain.
I have updated and repaired several items over the passed years.
1. Replaced broken exhaust manifold.
2. Removed cat. Converter.
3. New sensors.
4. New throttle body.
5. New alternator.
6. Cleaned out intake manifold.
7. Added oil/water catch can.
8. New pressure release oil cap.

Question I have is, my gauges jump sporadically but only during the winter.
GMC dealer first said it was the computer, then said it wasn't after replacing.
Then they said the culprit was the alternator. After the new alternator was installed problem went away for several weeks. Today I used cruise for the first time and it started again. It started the last time when using cruise also. Any ideas? Also remote start hasn't worked during g this issue.

3. New sensors. Which sensors?
4. New throttle body.

7. Added oil/water catch can. When did you install, results?
8. New pressure release oil cap. What type of cap and when?

Thanks for sharing your maintenance history, would be great to know the mileage for the major repairs. Intermittent and unusual electrical problems can sometimes be attributed to corrosion of grounds. Are all your gauges jumping or just certain ones. Are any of the warning lights also flashing intermittently?

yes all of the gauges jump.
Its the 2.4L engine, I replaced the O2 sensors, I installed the catch can after going to GMC because I was dumping oil/water out of the air box where the pvc hose enters, it then goes they the throttle body and into cylinder 1 or 2. The catch can works great I dump it once a week and it's almost full mostly water GMC says that's condensation and there's nothing you can do about it.
Took out the catalytic converter because GMC kept saying that it was clogged and needed to be replaced, but that ended up being the throttle body. And yes the traction control sensor light comes on and it shuts off when the gauges start jumping. The new oil cap was just a precaution in case the original PVC set up wouldn't clog and blow the main seal
Which happens quite often on these cars.

I would recommend the GM FC219 cap. It will not vent prematurely, and maintain proper flow in the PCV system. If you keep you catch can drained and check often you should not have to worry about over pressure in your crankcase.

I will be posting a procedure and pictures of a fitting I will be installing in my camshaft cover. This will allow owners to spray valve cleaner into the PCV orifice and help keep it clear of carbon.

You can sign up for online access to your engine vehicle service manual for only a few bucks per month. i use Mitchell1 and it has been a great help. You can find and check your vehicle grounds, especially the one supporting your instruement cluster.

The cap I have is the actual delco fc219 vented cap. It was suggested in the bulletin by GMC in Upper Northern cold climates where there is an issue of the PVC line freezing.

No battery has been replaced and rechecked. Interesting though this weekend I was cleaning out my catch can and I started my car without plugging in the hose from the catch can to the airbox and the car started and ran, but if you unplug the hose from the valve cover where the PVC is the car won't run and the gauges jump so I'm wondering if the PVC filling up with condensation and oil was the cause of it. I'm going to try driving it with the dump valve on the bottom of the catch can open and see if that alleviates the problem. I move my catch can lower, because while it was catching a ton of condensation and oil there was still some condensation going up through the hose into the airbox.
