The hydraulic braking system on your car is very complicated. Without all of the various components of this braking system working together, it will be very hard for you to...
Your car’s engine is a very complex piece of machinery. In order for it to function properly, there are a number of different components that will have to work together. Among the...
Winter can make for tricky driving conditions - just starting up your vehicle can be a bit more of a chore. When the engine is cold, it takes a few minutes...
Not only does the EGR (exhaust gas recirculation) system in your vehicle cut down on emissions, but it also helps to make your engine run more efficiently. However, in order for...
The cruise control vacuum reservoir is an air bladder that stores a supply of spare air that is vacuum pressured for when the primary vacuum runs low. This part is...
Without a properly working braking system, it will be nearly impossible to avoid being in a wreck. Most people fail to realize just how important their braking system is until they are...
As you drive your car, your engine draws in massive amounts of air which it then mixes with gas and ignites it to keep the engine running. The vacuum created as a...
The sound may be due to a vacuum leak and that would include the PCV and EGR systems. There are other possibilities but initially the latter possibilities would be considered first. To get this problem investigated and resolved, your best...
It is possible to temporarily seal air (vacuum leaks). Any method that best creates a seal can be used. In particular, RTV sealant which is flowable can be used to seal a non moving crack so long as the surface...
Hello, thank you for writing in. Unfortunately, the picture you tried to add did not come through. If you are trying to find a particular part, you will want to determine what it does first. Since you are dealing with...
The pop you heard was probably a backfire through the intake. When that happened, it likely blew a vacuum hose off of the intake. Now the engine has a large air leak that is causing it to idle high and...
Hi there. Check for any vacuum leaks that the engine may have. Look for any vacuum hoses or ports that are not connected. Vacuum leaks on the engine will contribute to the engine having a higher idle. If the vacuum...
Without knowing the engine size and vehicle having this problem I would have to say that you have an engine vacuum leak in an intake gasket or seal. You should have the computer scanned for any lean codes then have...
If the brake system was working before and now the brake pedal is hard and the front calipers are not moving, then the brake booster has failed (which is the hissing sound that you are hearing) and there seems to...
The issue sounds like the timing belt is put on 180 degrees off making the exhaust the open when trying to start and the intake open when trying to compression. This will cause a vacuum sucking sound as the vehicle...
Toyota vends metric vacuum hose and it is best to buy vacuum hose from Toyota. Toyota sells the hose bulk and in various lengths. The only things to be mindful of are to make the correct connections (i.e., don't connect...
The vacuum is due to the (PCV) Positive Crankcase Ventilation valve being plugged up. I recommend replacing the PCV valve and the issue will go away. When the PCV valve is plugged up, the engine crankcase cannot breathe and causes...
Hello. There are few things that I recommend you have a technician inspect. In order of probability your vehicle may have a bad mass air flow sensor, a bad crank position sensor, a bad throttle position sensor, or restricted fuel...
The IAC (Idle Air Control) valve is required to have a vacuum line on it to work the engine properly. The line from the carbon box filter is supposed to be hooked to it, but it may be damaged. Take...
Hi there. If the problem started after changing out the intake manifold on you engine and the car is new, then the issue is to be a vacuum leak on the engine. Check around the manifold for any loose bolts,...
Check to see if any vacuum lines were disconnected when your engine was serviced. A vacuum leak can cause the engine to have a loss of power under a load. If all of the vacuum lines are good, then the...
Check the exhaust system for any leaks before the oxygen sensors. This can contribute to having more oxygen in the exhaust stream causing the sensors to register a false reading. If there is no leaks in the exhaust, then check...
Hi there. Check the fuel pressure on the fuel rail and see if there is at least 30 psi. If the fuel pressure is low, then either the fuel filter is plugged or the fuel pump is not producing enough...
Check to see what on your exhaust system is hooked up. If your catalytic converter is hooked up and the pipes are hooked to the engine with good gaskets, then as long as the sensors are working, there is nothing...
Sounds like there is a vacuum leak that is causing the engine to rev up high. If there is no vacuum leak, then the Idle Air Control Valve could be stuck causing the engine idle to fluctuate on startup. I...
Check the brake booster for any vacuum leaks. The brake booster check valve could be split, the brake booster supply vacuum hose could be loose or split, or the brake booster diaphragm could have a slight tear or a pin...
Hi there. There is an issue with the engine having a vacuum leak and the may be cruise control is coming on to accelerate the engine. First check for any vacuum leaks on the engine. If the engine is running...
