You need to pull DTC's with a scanner. Most likely since the car is jerking, the VSS (vehicle speed sensor) on the transmission is bad.

Now people are modified, are generally using LED headlamps. LED headlamps because of bright and power-saving special, by the owner's favorite. Take the market is now very popular, "nine plus a car LED headlamps E2", the power is 33W, but the brightness is the original halogen bulb 3-5 times.

Q:Why are some antivirus engines light as a feather and possess no impact on system performance while others bog down the system? What is it about these security products' programming that creates this variation?

It completely depends upon the antivirus configuration and how it is made. Some antivirus tool slows down computer system and takes most of the memory space; while some work silently in the background without disturbing any process of your system. Like Windows Defender, Immunet Plus Antivirus, Bitdefender, Avira, AVG etc. are some examples of light virus protection tool which does not affect computer’s speed or any of its process.

Q:Why on lots of semi auto shotguns, do u have to turn over the gas piston to hoot light and heavy loads? Why is that? What shotguns shoot light 2 3/4 and 3in loads without switching the gas piston? That shoots accurate and reliable?

Not sure which make of auto-loader you would be referring to. My favorites are the Remington 1100 and 11-87 and the Winchester Super X-1. Those have self-regulating gas systems that require no changes. The only gun I have used where you need to turn anything around is the recoil-operated Browning Auto-5 and Remington model 11. Those use a series of brass friction rings and bushings to regulate the recoil system.

Other then the light coming on there are no problems i can see with this vehicle.ANy and all answers will be helpfulThanks

The check engine light comes on when a sensor reads out of the allowable range. It could have been caused by something simple, such as not turning the car off when you were getting fuel (setting an evaporative emissions system code), or it could have been caused by an engine misfire, or other problem. Have the computer scanned for codes, many auto parts chains will do this for free. The code will tell you what the problem is.

Q:Lately I have been having trouble with my Honda Accord‘s battery draining itself after I turn it off. Subsequently I have to get somebody to jump it when I want to drive it around. What could be the problem, and what is a cheap and effective way of finding out how to trace the problem and fix it?

sounds like you have a seal perished in the master cylinder or the wheel cylinders,this will cause fluid to be black.check if there is fluid on brake shoes
