Here is for the 4.2l ENGINE

A rod problem is a steady knock which increases with rpm. More likely you have a plugged air filter , a plugged fuel filter or a vacuum leak, ( vote fuel filter , people never change those often enough)

the release at the bottom of hatch can be ---rusted normal in northeast --- linkage popped or broken --linkage clip popped or broken --- need to crawl into back and remove the plug [ lower center of rear hatch panel will need a long screw driver and light will see linkage and latch push down on linkage arm and push open hatch when opened you can remove the rear panel and assess the problem but lube the latch and upper window latch

With as many sensors as that thing has, go to Autozone and ask for a free diagnostic tool check.

It is nothing to do with the canister or associated pipework. There would be no problem if the filler pipe entered the tank at the highest point but mostly they don't. Realistically the problem is like filling an old-fashioned teapot through the spout if the lid was sealed down tight and there was no vent - once the level has risen to a point equivalent to the top of where the spout enters the teapot a pressure begins to build under the top that resists further filling. To overcome this problem in the fuel tank and to allow complete filling, the high points have a vent and each vent is joined together by a hose that is terminated at a vent in the filler pipe at a height above the tank top. When fuel blowback happens during filling the cause is mostly one or more of those vents or hoses is blocked or squashed or otherwise damaged...

I would check all window and door seals.

Check the belt tensioner and the idle pulley... (looks just like the pulley on the tensioner, but bolts straight in.).. - from experience...my single pulley was bad... after replacing the tensioner TWICE... (duhh!!)

there will be codes but the scanner they used was not the right protocol to read them take it to an accredited professional auto transmission specialist shop and get it properly diagnosed it will not need a new transmission as it is servo/ solenoid --tcm or TR unit problem

Disconnecting your battery on our platform has a habit of blowing actuators. Takes quite a bit of time to replace them, not hard, just takes forever to get to them in the dash.

A few things....there are 2 fuse boxes to check, one in engine compartment, and one under back seat drivers side. 2nd, check and see if your socket is getting power. 3rd, there is a recall for the rear brake lights, so if all else fails, call the dealer with your VIN #.

Question isn't clear. If you want to BUY pigtails, rockauto is the best place to buy them.

Have you checked under the hood to see if the cap is on the overflow/expansion tank ?

They make a kit to repair it, watch the video. GMC Envoy shift cable the easiest way to repair Kit includes replacement...

Very common problem, it's the plastic bushing that breaks. It's Dorman part # 14057.

It would give the plug gap on the Vehicle Emission Control Information label (VECI label) that is pasted to the radiator support or under the hood. A long white sticker label, with emissions information for that particular vehicle. The spark plug gap is always listed there.
