Q: Vehicle idles poorly

The first thing you'd want to think about is: does it do it in reverse and drive? If it only does it in reverse, you either got a problem with the transmission or your differential, the rear differential. One of...

Hello. If just your tail and license plate lights are not working, I would first check to see if any fuses (https://www.yourmechanic.com/services/fuse-replacement) are blown. It may be possible that both of those exterior lights are on the same circuit, and...

Hi and thanks for contacting Your Mechanic. The wiring harness to the mass air flow sensor (MAF) could have a break in the wires. Disconnect your battery and remove the harness to the MAF and your computer. Use a digital...

Hi There, What you have described sounds like your serpentine belt (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement) may have come off. As you may know all of the accessories (ie alternator which charges the battery, power steering and the water pump) are driven by the...

There are several things that can cause this kind of sputtering to happen, however one that is very common is in fact the camshaft position sensor failing which can cause problems with ignition timing resulting in sputtering as you describe...

P0011 (https://www.yourmechanic.com/article/p0011-obd-ii-trouble-code-camshaft-position-a-timing-over-advanced-or-system-performance-bank-1-by-jay-safford) means that the intake camshaft is more advanced than what the ECM has commanded. Typically, the mechanic would resolve this by checking the electrical connectors, wiring, or valve issues for the camshaft oil control valve for the engine's...

Hi There, The swirl control valve is actually a part that helps to control the vaporization of the fuel inside the intake passages as it is passed through to the combustion chamber during low idle or cooler operating temperatures. As...

The problem sounds like you have a piston hitting a valve. You will need to try and put the number one piston on top dead center on it compression stroke and check camshaft timing to see if it is in...

A large voltage drop is going to be a bad cable or connections either at battery or starter and engine grounds. Try doing a voltage drop for the positive and negative cables and also try using a jump to the...
