Loss of power in certian areas

Pulled a wire now the speedometer,rpm,gas gauge, trip doesnt show, dome lights, radio doesnt work niether do the electric locks . The only thing on the dash that works is the oil pressure gauge and the battery gauge and the service engine light is the only light that comes on when u start it up.

My car has 15300 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
I can’t tell you exactly which wire it is that would cause this, but whatever wire you pulled is very likely to be the cause of all these issues. It sounds like it was a main power or ground wire for multiple systems, since powers and grounds are often shared across multiple circuits. If you’re unable to properly repair the wire yourself, I would suggest having it done by a qualified professional, such as one from YourMechanic. They will be able to diagnose the source of your electrical issues firsthand and fix the problem accordingly.

VCM (Variable Cylinder Management) is fuel-saving technology that automatically deactivates 1/3 or 1/2 of the cylinders, according to the driving conditions. This saves fuel and lowers emissions.
There have been issues in the past with cylinder deactivation not work as well as the manufacturers might have hoped. However, with new vehicles cylinder deactivation does not usually cause those problems. Instead, it allows you to take advantages of premium power when you need it and save on fuel when you don`t.
Check the MAF sensor and clean it out with dry air. Then put it on and disconnect the battery for 12 minutes and hook it up. This will clear the computer to want to relearn itself. Then drive the vehicle and see what happens.
A clogged or failed exhaust gas recirculation or crankcase ventilation valve or faulty oxygen sensor can send the wrong signals to the computer and cause misfires.
Diagnostic Trouble Code P0300 can set if you have faulty spark plugs, low compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injectors, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft …

Loss of power few minutes after starting the car.
ANSWER : Hi there. Actually, the OBD-II error code you listed, P0233, is a generic OBD-II code that is triggered when the engine control module (ECM) detects that the secondary circuit to the fuel pump has an intermittent voltage when the fuel pump relay is turned on. The fuel pump secondary circuit powers the fuel pump and can cause a no start or the engine to suddenly stall while driving, which might be the source of the stalling issue you’re experiencing.

I am replacing my power brakes booster and need some advice about removing the power unit from the bell crank.
ANSWER : Hi there. When removing the brake booster from a vehicle, you will need to remove the master cylinder and cap off the hydraulic lines. Then go in the cab and remove the pin from the bell crank and unbolt the 4 bolts that hold the booster on. Then remove the booster. Do the opposite to install the booster. If the bell crank pin had a cotter pin to secure it, make sure that you use a new cotter pin. If you need further assistance with removing and installing a brake booster in your vehicle, then seek out a professional, such as one from Your Mechanic, to help you.

Check engine light on, power loss in fourth gear
ANSWER : Many different faults can be attributed to your 2008 Chevrolet Aveo5’s loss of power. In cases where the Check Engine Light has not set a hard code, it can be a bit harder to pinpoint the issue.

If the spark plugs were replaced when the Check Engine Light was able to be read, I can only guess that the code was for a misfire without knowing the actual code. The most likely causes of a loss of power would be a misfire, spark plugs, fuel pump, fuel filter, oxygen sensor, MAF sensor or vacuum leak. A qualified technician, such as one from YourMechanic, will be able to diagnose the vehicle’s loss of power and perform any repairs required.

Loss of power using turbo
ANSWER : It sounds like the vehicle is going into limp mode. This occurs when the powertrain control module (PCM) (also known as the electrical control unit) has determined there is an overboost condition. The computer disables the turbo to prevent damage from occurring. There are many potential causes for an overboost condition, with a failed turbo being just one of them.

Some other possibilities include vacuum leaks, a faulty vane adjustment solenoid, faulty turbo actuator or a bad MAF sensor. There is a technical service bulletin (TSB) # 21-07-65, which advises to check for vacuum leaks before replacing the turbo.

If you would like a second opinion from the dealer, I suggest you give the team at YourMechanic a call to inspect your loss of power condition.

I have loss of power after 30mph, hard to shift.
ANSWER : Hi there. It is very possible that the minor exhaust leak has grown into being the primary cause of your acceleration issue. The exhaust system is engineered to efficiently expel exhaust gases from the combustion chamber through the exhaust system and out the tail pipe. This creates compression and when there is a leak, the internal engine’s combustion is significantly impacted; which can cause these issues. However, there are other fuel or ignition system components that impact acceleration as well as transmission problems as well. It might be a good idea to have a professional mechanic complete a car is slow to accelerate inspection at your location; so they can determine what repairs would be needed to resolve this problem.

I have white/bluish smoke coming out of the exhaust occasionally. I have no power loss and it happens infrequently.
ANSWER : I suggest you study the smoke and try to recognize a pattern. It might mean that you have to spend a lot of time looking in the mirror, so try not to be unsafe. If you are having a problem with valve stem seals, you may experience the smoke more when you are letting your foot off of the gas. Decelerating raises the engine vacuum and draws oil past the valve seals and into the intake where it goes on to be burned. Stem seals will also be the diagnosis if you have a big cloud of smoke on starting a car that has been parked several hours or overnight. If you have a problem with piston rings, you will see more smoke when you are accelerating and demanding more power from the engine. Either way it’s going to be a big expense. Many people prefer to put off the repair until the oil starts to foul the spark plugs and the engine begins to skip. If you want to be sure what is going on with your car, contact Your Mechanic to have a technician come to your home or office to check out your car and give you a recommendation.
