My check engine light has started coming on while driving--today the car started jerking while I was driving it---was told it may be the camshaft sensor.

My car has 154000 miles.
My car has an automatic transmission.

Hi there. When your car is jerking around, this means that the engine is having a misfire and causing the engine to stumble making the vehicle seem to jerk around. Check the camshaft position sensor for any damage and if the harness is secure to it. Check the spark plugs and wires to see if they have any burn marks on them. The burn marks are hot spots that the spark plug or wire got too much voltage when applied. If the camshaft sensor and ignition wire set are okay, then check the mass air flow sensor (MAF) and see if its dirty. Replace any part that is damaged or is burned. If you need further assistance with your vehicle jerking around, then seek out a professional, such as one from Your Mechanic, to help you.

Q: My 2003 Toyota Sequoia starts then dies and does this a couple of times until it stays running. It only does this when it's cold.

Although it is a little cumbersome, you could try to rule in or out a fault in the fuel delivery system by having an assistant quickly introduce "starter fluid" into the intake right at the point (very quickly, of course)...

Q: Car takes 7-10 seconds to turn over and crank. VDC and Slip Lights are on.

Hi there. Typically, when a vehicle is hard to ignite, it's related to ignition timing. However, there is no need to spend $2,500 from the dealership on that type of repair. The best thing you can do is contact one...
