As 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 result is fairly constant depending on throttle...
The 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 retain the stopping power of your car. The brake...
In In order for a car to have the brake power that it needs, there will have to be a sufficient amount of vacuum power. The engine of a car produces a good bit of vacuum power, but it will...
If a vacuum leak occurred right after the carburetor was replaced then the gasket underneath it was not installed properly, is missing, or the vacuum hoses were not installed correctly. Prior to removing the carburetor I would double check the...
Hello. If the shifter is moving fine and the truck responds to the shifter position but does not move when the transmission has more than likely failed. If there is no response at all, then it may be the shift...
There can be many reasons for an engine to stall. Since the Check Engine Light is on I would start with scanning the computer for codes and moving forward with a diagnosis from there. You may have a vacuum leak...
Hi there. Check the fuel pressure regulator and make sure that its working and plugged in. Put a fuel pressure tester on the fuel rail and make sure that there is good fuel pressure of 45 to 65 psi. If...
This may be a sign of a vacuum leak. A vacuum leak can be one of the most frustrating and difficult problems to diagnose. High idle speed is a common sign and stalling is another. Confirmation of an engine vacuum...
There is a 1 hour minimum charge for a service for a service call in most cases. If the hose is a factory preformed hose then it may have to be purchased from a dealer and then installed for you....
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...
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...
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. This is a very common failure on vehicles like yours. So common, in fact, that there is a technical service bulletin (TSB) on it. The TSB is XT303-13 and it addressed the hissing sound from under the hood, as...
The idle control valve may be stuck or you have a vacuum leak. Try to disconnect the vacuum lines to the EGR valve to see if it still stalls. This may be due to problems in the vacuum system. Try...
Unfortunately, this is something that older cars suffer from. Vacuum lines are made of rubber. Over time, the rubber in the engine compartments begins to get hard and brittle. Once this happens it no longer performs its job properly and...
Hello there, thank you for asking about your 1986 BMW 635CSi. It sounds like you've checked all of the low hanging fruit. The previous owner may be right - some vehicles (only German ones come to mind) can develop a...
If this is not related to any vacuum leaks, the next place to check would be the brake booster itself. As you press the brake pedal down, a shaft inside the brake booster moves forward into a diaphragm, which separates...
Hello, thank you for writing in. The most likely cause of the issue is a bad MAP sensor. Before changing it out, you will want to check for any other obvious signs of problems. These would include frayed or damaged...
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...
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...
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...
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...
