2007 Chevrolet Chevrolet Silverado 1500 - Answered Questions & Fixed issues

Perhaps, but keep a close eye on your Oil Level - more likely burning old - Get your compression checked, likely a cracked Piston Ring.

Usually this is a loose or improperly sealing gas cap. The code will clear out (iirc requires 3 starts from cold) or get your local autoparts store to clear it for you. Gas cap is easiest and cheapest thing to try. It can also be a leaky evaporation canister, leaky vacuum hose, leaky fuel filler hose...etc. basically as part of the test cycle it checks to see if the evaporation system holds a specific vacuum for a specific time. Yours failed the test.

Go to this Google web page and open the pdf file it is the first item on the page. Google

Seized the engine , put socket an breaker bar on crankshaft pulley an see if you can turn engine by hand .

You have Sevier miss fire ,if you keep driving it your going to melt the catalytic converter . You need to take it to a ASE certified repair shop.

oxygen sensors have a connect close handy to the unit and that wire can be cut or damaged if the incorrect removal tool is used look for a connecting hanging close by

That's an emissions code. It's sucking in too much air. Start with checking for vacuum leaks, air filter may not be sealed, could be idle air control valve, throttle pos. sensor. Many possibilities. Start with the simple stuff, you usually get it from that. good luck.

Needs regassing thats all ,all Ac R134 systems lose gas after a couple of years ,its so corrosive that in the end it rots the alloy pipes out from the inside after 20 yrs

Preliminary Procedure Remove the knee bolster. Refer to Knee Bolster Replacement 1 Body Control Module Tip

1. Remove the BCM cover.
2. Disconnect the electrical connectors.
3. Press on the tabs to release the body control module.
4. If a replacement module is installed, program the module. Refer to Control Module References .
5. A new body control module (BCM) must be programmed with the latest operating software and vehicle calibrations. Ensure that the following conditions exist in order to prepare for BCM programming:
6. The battery is fully charged.

   ?€¢ The ignition switch is in the ON position.

   ?€¢ The data link connector (DLC) is accessible.

   ?€¢ All disconnected modules and devices are connected.

   Programming the BCM Important: The vehicle will not start and many other functions may not operate properly if a replacement BCM is not properly set up. The following procedures must be followed:

   1. Programming the BCM
   2. Learning the restraints ID
   Important: After the procedure is completed, the personalization settings of the BCM are set to default settings. Inform the customer that the personalization must be set again. Refer to Service Programming System (SPS) for more information

You said you hit something. Carefully check the transmission linkage to make sure that it is properly engaging. Crawl underneath and have someone move the linkage while you examine the movement. If something got misaligned when you hit whatever, it is conceivable that the tranny is not properly engaging due to this. Could be a simple fix. Good luck.

Make sure your drive shaft is still intact and make sure that both of your axles are all of the way in.

Make sure the shoes are not over adjusted and too tight.

Probably blown speakers (do you have a teenager?) Access speakers on at a time and you can use a AA battery to test each. Hook up wires to battery and jump to speaker to see if it clicks or moves.

P0191 is injector pressure sensor system performance. Nothing on the other code with the letter mixed in. I would erase it and see if it comes back.

Loose wire or blown fuse.

no sounds like shift cable is binding shoud replace

Try disengaging the "Auto Lock" feature in the Driver Information System when shifting in/out of Park and at a certain MPH. If that keeps it from doing it, you know the BCM Body Control Module is controlling the action. It could be it "thinks" it's unlocked when it not. May need to replace the power lock assembly. You could also try taking the battery cables off to reset the PCM/BCM. That may fix it too. Worst case, it is the BCM, and they are not cheap. Good Luck!

Probably needs a tune up. plug wires, spark plugs, distributor cap and rotor. Also change the air filter and fuel filter and crank case filter as well as PCV valve (positive crankcase ventilation valve) this valve scavenges harmful acid deposits or blow by and reburns it and sends it out the exhaust pipe. Examine everything before you buy new if the plugs look good just reset the gap if the wires look good move on to the cap and rotor. you can find images on the internet to look at to compare condition of most parts at least just by look. if that does not do the trick you may have to take it to a mechanic. be sure you tell them all you have done. start with plugs cap and rotor then fuel filter. Check the air filter if you cannot see light through the paper element replace it for sure. the sputter can indicate not enough fuel or insufficient spark to ignite the fuel. spark plugs can do wonders if they have not been changed for a long time. the fuel/combustion deposits rob the spark from jumping the gap which ignites the fuel under higher cylinder pressures. when the spark travels directly to ground without jumping the gap the cylinder makes no power.

If it is a limited slip rear end, it is trying not to slip as you corner and may be grinding itself to death. It can be caused by low oil, water in the oil, dirt or misalignment. You should have the correct fluid on hand before taking off the cover to see how much damage you have.

Most likely cause is the IPC is faulty. The only fix is replacing it. Dorman offers them pre programmed for around 300 bucks.
