Question edited for clarity.
Question moved to model category.
Black Smoke is rich mixture
Blue Smoke is oil
White Smoke is Steam
What is this 'Trumbler' that you changed?? Not even Google has a clue!
Are you losing coolant? Did someone put Windshield Washer fluid into the engine oil filler? You are burning water. The ECM doesn't like it so it it shakes. At idle there isn't as much pressure to stop the water entering the combustion chamber. Likely a failed cylinder head gasket. You can do a pressure test and there is also a test that identifies exhaust gases in the coolant.

2007 Chevy Avalanche 5.3. Location of fuel filter please?
The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.

2002 Chevy Cavalier not getting 12 volts to the fuel pump only getting nine
Your better off finding the cause of the issue. Modern cars have so many sensors and electronics 'bypassing' electrics will become a Huge headache and put a massive dent in your bank account if it goes wrong!
Have you had the battery "Load Tested"? This is where they put a heavy voltage drain on it and see how it copes with it. How old is the battery? A battery can still hold 12 volt but be weak when it's got to supply power to high drain parts like the starter motor. Generally batteries are considered 'Old' when they are over 5 years old, especially on bigger and higher mileage engines.
The fuel pump relay should get power as soon as you turn the ignition to the second position so it can prime the fuel system before you start the engine. I've posted an answer to your Fuel pressure test question and in the video I've attached he shows you a quick "cheat" to test if it's the relay.
2007 Chevrolet Monte Carlo. It moves when in reverse and low gear. But when it's in drive it just revs up but doesn't move. However, I'm not getting any transmission codes.
Thanks for the information about checking transmission fluid. Unfortunately we don't get Notifications when they are made up there.
I was hoping that @Jeff Armer would take the question. He is a full time auto electronics tech and just the person you need. I am guessing he didn't get a notification either.
The image is difficult to read even zooming in on my computer, but you have multiple communications and voltage errors and guessing the problem one is to the Body Control Module, but you have multiple errors. That means when the computers tell the transmission solenoids to move it doesn't happen. An auto electrician with a professional grade bi-directional scan tool computer can command transmission solenoids to operate and verify that they did. That would be the starting point. This is not something you can fix yourself and Jeff seldom says 'take it to a transmission shop', note that this is not a normal garage, but a place that only does transmissions.

Where is the fuel pressure regulator located on a 2014 Chevrolet Impala 4 cylinder
The 2014 Chevrolet Malibu with the L4-2.5L
engine does not have a 'typical' fuel pressure regulator. This vehicle has a fuel regulator valve (same function, just 'smarter' than a regulator). The pressure relief regulator valve replaces the typical fuel pressure regulator used on a mechanical returnless fuel system. Output drivers in the ECM provide the pump control circuit with a 12?V pulse-width modulated (PWM) signal, which regulates fuel pressure by closing and opening the control valve at specific times during pump strokes. On this vehicle, the regulator valve is built into and part of the high-pressure fuel pump. The high-pressure fuel pump is located on the rear, driver's side of the engine.

Torque specs for inner joint bolts to diff. 2004 chevrolet 2500 4x4 front axle
The torque specifications for the inner joint bolts that connect the front axle to the differential on a 2004 Chevrolet 2500 4x4 may vary slightly depending on the specific model and components used. However, I can provide you with some general torque guidelines.
Please note that it's essential to consult your vehicle's service manual or contact a qualified mechanic for the exact torque specifications, as they can vary depending on factors like the specific front axle design and any aftermarket modifications. Here's a rough estimate:
- Inner Joint to Differential Housing Bolts: Typically, the torque specification for these bolts is in the range of 85-100 lb-ft (115-135 Nm). However, it's crucial to verify the exact torque value from your vehicle's service manual.
Always use a reliable torque wrench to ensure that the specified torque is applied accurately, and follow proper tightening sequences and procedures as outlined in the service manual to prevent over-tightening or under-tightening, which can lead to problems with the front axle and differential.
