Car is jerking while driving on the highway and when car is stopped at a light it cuts off and the stern wheel gets stiff

The Hydraulic block mounted to the transom.

Sounds like a misfire. But honestly it could be anything. If the check engine light is on that could point you in the right direction

What year? What model? Jerking... when? Where do you feel the jerk? Do you have a "Check Engine" light on the dash?



You may have just lost a front axle. The rubber boot around the CV joint cracks, and dirt gets in and ruins the CV joint. This shows up as a sideways jerking in the steering wheel, rapidly getting worse and worse. It feels dangerous, and it IS dangerous. If it\'s allowed to continue, it could break the axle shaft - you certainly don\'t want that to happen on the highway.



If you\'re NOT talking about a sideways jerking in the steering wheel, please desribe what you DO feel, and when it happens, and if your "Check Engine" light comes on. It might possibly be nothing more serious than your air conditioner turning on & off.

check for oil level in the reservoir. Check the drive belt for condition and tension. BY turning the wheel from lock to lock (recycling the wheel )you are in effect bleeding air out of the system

When it doesn't start, check for spark from the coil.

Hard to say without a visual inspection. Have them rechecked by the shop that did the install. You may need new rotors. The rotors may have been cut beyond discard allowance,

It sounds like you have a bad MAF (Mass Airflow Sensor). This is in your air inlet tube, pull this out and check to see if there is any corrosion on it. If is one that has a coiled exposed wire, then ensure that the wire is not broke.

get a scanner check code sound like vechicle speed sensor.

air bubble in gas lines or a big ******** id say get it flushed
