My apologies but this scenario would be much easier to understand if you were to indicate the direction of travel for each vehicle such as N, S, W, or E. Also, the outcome of this scenario is likely to be...
Hi there. This vibration could be caused by a number of things. However, the first place I would look is the driveshaft and u-joints. The driveshaft is used to transfer engine torque from the transmission output shaft to the rear...
Hello there. Lack of fluid is the number one cause of transmission failure. If the transmission went without fluid for too long, it could be severely damaged. The only way to tell if a transmission is severely damaged without disassembling...
Hi, thanks for writing in. This is a sign of bad or warped brake rotors. When brake rotors get hot due to friction and then col down repeatedly, they can develop low spots in them which can cause them to...
High mileage engines leak oil into the combustion chamber through worn out valve stem oil seals, worn valve guides and ill fitting piston rings. If a substantial amount of oil is entering the combustion chamber the plugs will quickly foul....
Hi there. Chances are the latch assembly is either faulty or the lever linkage has become detached. The door panel will need to be very carefully removed from the inside and the latch and linkage assessed. If the latch is...
Either the transmission is slipping harshly or something broke inside the transmission making the gear drives not work properly. Make sure that the transmission fluid is full and red in color. If the fluid is full and red in color,...
Hi there. Diagnosing an electrical issue without inspecting the vehicle is very difficult. However a few things you might want to check on your BMW includes the battery, alternator or other electrical relay's such as the battery cables. The best...
Hello: Anytime you swap out a motor, it's incredibly important to double check that all components correctly align and are compatible. The truth is that without being there to physically inspect your Maxima, it's impossible to diagnose why your engine...
Hello. I would need to know what kind of Ford this is to know for sure what may be going on. Most of the time on these older Ford models the issue is fuel-related. It may be a result of...
This is an electrical problem that is resolved using what is referred to as a "circuit trace". A circuit trace pinpoints the wiring (or component) fault that accounts for the misoperation. If you have the factory wiring diagram in hand,...
Hey there: There are usually two different mechanical problems that cause the symptoms you're describing with your Pontiac Firebird. The first and most common is a problem with the ignition coil, (especially in mid-90's GM V-6 engines) or due to...
Hi Adrienne. Thanks for contacting us today. In most cases, when an engine will crank over but will not start, the fault is with an ignition timing or fuel system component. This can range from crankshaft and cam position sensors...
Hello. The most important sign is when you drive there isn't any vibration. If the source of your question is due to a vibration and you suspect the drive shaft, the best way to check it is to put the...
Hello. Unfortunately there is not a switch for the seasons on this vehicle. If it is not blowing cold then it is usually an issue with low refrigerant. The system gets low due to a leak and the compressor will...
Hello, the first thing to do is check the oil level and get that correct and then diagnose the overheating concern. It will probably need to be jump started to get it going. The cause of the overheating must be...
If you have just installed a new fuel pump and can not hear it come on when you turn the key to the run position (not the start position), you may have a ground issue. You can also perform a...
This is not an error. The crank shaft goes around two times to the distributor one time. This means if you put the number cylinder on the compression stroke top dead center and line up the distributor then if you...
Hello. If your engine is backfiring and you smell gasoline then it is likely that your vehicle is running rich. Backfires can be caused by both rich and lean conditions, however a fuel smell is usually associated with a rich...
You may have a connection that is getting corroded and is causing intermittent connection problems. If the problem happens again then have the connection to the dashboard cluster disconnected and then add dielectric lube to connection and pins. At the...
When it comes to vehicles over 5 years or 60,000 miles, my preference is to drain the transmission through the pan and replace the filter, especially if the transmission has never been serviced. The sales pitch is of course that...
Hey there, thanks for writing in about your 2004 Jaguar XJ8. If you are getting a noise in the vehicle only between certain speeds, then you may have a transmission needle bearing or something like that in the transmission that...
Hi there. It is possible you may need to replace your thermostat. The thermostat opens when the car gets warm to allow more coolant to flow through the cooling system. When it fails, it can become stuck closed and will...
