Q: Car sucking air.

asked by on January 13, 2016

My car is sucking air somewhere, it runs rough and will not idle. I replaced the water pump, thermostat, timing chain, manifold gasket, and the crank shaft sensor.

You are correct in that a vacuum leak could cause a rough idle condition. However, your issue has many potential causes. I suggest having a trained mechanic with the correct diagnostic equipment pinpoint your problem.
