It could, but usually if the PVC is stuck the car will barly run if at all. Shake the valve it should rattle. If your still not sure pull the valve from its hole and with the engiene running put your finger on the end of the valve and see if anything changes
check the idle air control motor. Valve may need cleaning
Mineral deposits Or someone shut off a valve OR a washer or other debris blocked the line Or the tank is full and not calling for water
Sounds like your problem is the brake booster valve ...... When the valve goes bad it takes the vacuum away from the motor, and when you apply the brake the motor will stutter and when you pull it into gear it will usually kill the motor unless you are giving it a little more gas than you normally would to keep the motor running. The little valve is located at the booster...it will have a small vacuum hose that comes from the motor to the brake booster valve. The valve just pops into the booster, and can be found at some auto parts store.
Backfiring in any motor is either badly out of time or a burnt valve.
Worn valve train parts due to high mileage, lack of maintenance, abuse or contaminated motor oil (coolant mixing with oil).
I would not expect a valve cover leak to cause a car to stall. A valve cover leak can fill the spark plug area with oil which can cause rough running.
A D&C would not cause blocked fallopian tubes. If you got pregnant, at least one of your tubes was not blocked.
would a cracked blocked cause a car to bubble antifreeze inside the reservoir of a 97 ford taurus ?
NO it would not.
no but it may cause it to stall if exhaust is blocked
Would this cause the car not to start If the EGR VALVE is bad
wat the #@$!& is a valve cover ...who cares about sparks!!!!
