I cleaned all of the grounds I could find and I think it's fine now. Those ground wires are very sensitive. At first I took care of the G218 issue. Cleaned it and sprayed it with WD40 but that was a mistake. Before I didn't had any trouble with the powersteering and the stabilitrack system. But when I took it for a drive after the G218 modification it shut itself down while driving, gave a stabilitrack failure and the powersteering died. Today I cleaned it with brakecleaner and sandpaper and so far it's doing ok. So don't use any kind of spray or oil. just clean it and put it back together. Those ground connections are very sensitive.

thanks for the tip deepa. I'll check this groundwire too. any more tips?

thanks mikeyk101 for your reply. the ground issue you brought up is a known problem and that's why I already corrected this problem. I read the service bulletin you sent me and I don't have any of the issues that are mentioned. so maybe it's a dodgy bcm?

My 2014 silverado has a problem with the clock and date when I start it. This problem happens sometimes. I start the truck and everything works normal but the clock and date are changed just like if you disconnect the battery. Is it possible that there's a bad ground somewhere? And if so, where is this bad ground located? thanks.

Thanks for your reply. Your explanation of the afm system makes a lot of sense. I never had thought about pumping losses before and it's an eyeopener for me. The next step in afm is perhaps downsizing the engine displacement just like ford is doing nowadays with its V6 engines in trucks. But I hope that gm stays true to the mighty V8, which sounds a lot better too thanks guys.

but a simple decompression system just like on a one cylinder motorbike and a injector deactivation isn't a simple solution?

so the engine not only collapses the intake lifters of 4 cylinders , it also shuts down the fuel injectors. but doesn't this mean that the cylinder is pulling a vacuum at the intake stroke? and pulling a vacuum like this cost energy, right? perhaps it"s a better idea to use the solution used on a big 4 stroke single cylinder motorbike. I'm talking about the decompression system that is used to lighten up the effort to start such an engine. this system opens the exhaust valve at the compression stroke too. I'm not an engineer ,I'm just trying to figure this out with the help of you guys

Hi guys, I have a silverado truck with a 5.3L engine and I wonder how the active fuel management works. I know that it uses lifters which can shut down it's cylinder but my question is: why use all of the hardware, like special lifters and stuff, while it's easier just to shut down a fuel injector instead? Just turn of the voltage to the injectors of 4 cylinders during V4 mode instead. Is there a reason why my simple idea does or does not work?

Another design flaw from GM... So the tip you guys give me is: don't hit stuff with the outside mirrors. It will damage them. Thanks for the input guys.

So if I hit a tree during offroading the mirror will fold in but only if I drive forwards. If I drive backwards the mirror will break. But the mirrors don't like it very much? It's better to fold in the mirrors in during offroading in the woods?

Hello guys, I have a 2014 chevrolet silverado LTZ with the standard mirrors. Not the towmirrors. They fold electric, but what happens when the mirror is struck by an object like a tree? Does it break off or does it fold and can it fold to the front and the back? I'm allways folding my mirrors in when I park at a buisy parkinglot cause I'm afraid that someone wil walk against the mirror and damage it. But do I have to worry that something wil break?

Gm runs very high transmission temperatures because of the thermostat that is used. normal operating temperature is round 190 degrees and gets higher when it's hot outside. Heat is a bad thing for automatic transmissions so first let it run a bit cooler .I fitted a superior solutions transmission thermostat. It keeps the transmission temperature round 150 degrees. The other thing to do is check if your transmission oil has metal flakes in it. if so, your in trouble and you proberally need to rebuild the transmission.

Thanks for the reply ftwhite. I'm going to replace mine too. But because I'm from Holland I can't go to a parts-store and buy a throttle body for my truck. They just don't sell them here. So the only option is to order one on-line. I usually order parts at rockauto.com but do you know any other site where to order one? perhaps a ported one?

the throttle body isn't that expensive so replacing it is a good idea. do you need to reprogram the throttle body or is it just plug and play?

there are no fault codes stored. but when I use an all metal screwdriver, put one side on the throttlebody and the other side agains my ear, I clearly hear the ticking sound. so the sound is coming from the throttlebody. The next thing I can do is remove the intake assembly while the clickingsound is present. so I can see if the butterfly valve is moving with the clicking sound and go from there.

thank you for your reply jimcost2014 but what does CEL means? I'll take your advice of checking for some stored codes and post my findings as soon as I have the time to do so. the truck still runs great ,the only problem is the ticking. I don't want to be the guy who gets stranded at the side of the road because I ignored a problem.

is the throttle body a part that often fails? or is it a case of bad luck for me.

here's an update of the ticking issue. when I increase the rpm the ticking sound does not change. so it's not rpm related. the ticking is heard when the truck has been driven for about 10 minutes. when I shut of the engine after a say 15 minute drive , wait a good 15 minutes and then start it again, the ticking sound is gone. you can hear it but only once a minute or so. when I open the hood after a 15 minute drive it ticks but when I pull out the throttle body connector the ticking stops immediately and of course the engine goes into a sort of limp mode. so my guess is that the throttle body has something to do with it. so should I replace the throttle body for a new one or is it servicable?

early today I opened the hood while the engine was idling and noticed a clicking sound comming from the throttle body / intake manifold area. I think it has something to do with the variable intake system. the clicking sound is heard twice every second. does the intake manifold has an electric motor inside to operate the variable intake manifold? It sounds like the connection between the actuator and electric motor has something to do with it. the check engine light does not come on. the engine is a 5.3L and the truck is a 2014 chevrolet silverado ltz. does anyone have an idea what the problem is?

Hi guys, I'm trying to find a company who sells hidden winch mounting plates but got no succes. The only make I found is the rough country hidden winch mounting plate but to sent it to holland they ask $550. While the set cost $200. Does anyone knows an other company who makes these plates? Or is it a better idea to make something myself?

Hi guys, Here's a update of how things are right now. I tried to find someone in holland who could reprogram my transmission. After a long search I found a guy who works at the gm import dealer. He could help but asked a serious amount of money. So I did the math and bought my own hp tuner hardware. This was only a little bit more expensive than the gm guy asked. But now I can modify my software as often as I want and it's also usefull to read dtc codes and much much more. Got a tunefile from grumpy bear's contact and used it to modify the stock transmission software. Now lets hope that the transmission gets to go way past 100000mls. Thanks guys for all the usefull input.

Doesn't anyone know where the module is located? Lucky it's allmost summer so I don't need my seatheater now but I like to have nice warm seats next winter.

Got an E-mail back from grumpy bear's contact. He says that he machinnes the pump housing if necessary and puts in a transgo tcc kit and a transgo shiftkit. And after install he tunes the transmission with hp tuners. After all of this the transmission works great and stays that way. So I'm going to tune my transmission to prevent any problems in the future.

I send him an e-mail. Lets wait and hear what he's got so say. Thanks grumpy bear. I'll keep you guys updated.

Anyone?
