so the cold finally hit me here in NJ and being im off all winter, neither car has been fired up or driven in a good 2 weeks now.

headed out to take my mom to a dr's apt and the hoe is stone dead. ok, ill take the regal, super slow crank hardly started. so im off to buy a new battery and looks like after testing ill be getting the regal a pro rated new one, it cant be 3 years old yet.

came back tried to jump the hoe, was on cables for 15 minutes, only got a slow crank out if it, no fire. crazy how a battery will be just fine then dead as dirt with out warning.
Most vehicles I’ve owned will have a parasitic drain that will significantly affect the battery after 2 weeks. Some faster than that. I keep them on a trickle charger whenever possible, or pull a cable off.

How did it drive in the snow? Those A/T's?

Yeah, I've got 35x12.5 Nitto Ridge Grappler AT's. They did awesome–just put it in Auto 4x4 and used the cruise control. It was almost a complete whiteout at times but the Tahoe was a tank!

Main reason I stopped for the night is that my eyes were getting tired from straining to see through the snow.

Dont want to sound like a tool. But never use your cruise control in the rain or snow. Using cruise control in the snow, ice or even rain is dangerous because if your car hydroplanes or skids, it will accelerate and rapidly spin the wheels since it will be trying to maintain a constant speed. If this happens, it will be more likely that you lose control of your vehicle. The cruise control does not know that you lost traction. Just want to make sure you dont trash that awesome looking tahoe.

Went to clear my CEL codes yesterday and I couldnt get a scan tool to read on the truck (I just replaced the evap sensor on the intake manifold so i wanted to clear that code to see if it comes back)

I then did a little detective work and found that a penny in my cigarette lighter blew the fuse and the obd2 port and cigarette port share the same fuse. Swapped that fuse out and bam worked. Cleared the code...... but I found out I'm throwing the knock sensor code now.... one thing after another with this truck!!!


When will it stop!!!!!

Those are typical. Probably corroded.

Valley cover gasket, knock sensors & harness, RTV mod, oil pressure sender if you haven't done it in the last couple months (lol), valve cover gaskets & paint job, plugs & wires....

Already have it all in my Amazon cart lol. I'm not doing the oil sander I did it about 6 months ago.

My plans were to clean the throttle body, intake manifold, all ports, injectors and whatever grime I come across. Then replace the throttle body gasket, intake manifold gasket, valley cover gasket, and injector o-rings. Plugs and wires will have to wait, that's a other $100

Should I replace the cam sensor while I have the manifold off, even if I'm not throwing a code for it?

Also how important is the valley cover gasket?

installed new battery, had the regal tested shows 580 on cca and 12.25 volts, its on its way out. turns out to pro rate a battery you bought at advance auto on line and store pick up, you need to know the order #, so im off to dig through 3 years worth of advance auto emails lol.

ill be keeping this new on in the repair files for this truck now, wish i kept the last one from the regal.

So I do have to replace my knock sensors. I got some stuff to clean the intake ports and fuel injectors. Aso some red rtv I think I'm going to do the valley cover since I'll be there anyways.

But side note. What kind of OBD2 scan tools are you guys using? I was looking at this bluedriver scan tool which is bluetooth and $99 but iirc scans airbag and abs codes

It is a very popular choice and seems to do quite well. It is a great option for someone who isn't wanting to go the tech2 / bidirectional route.
