The two codes, P0736 and P0730 overlap to some extent insofar as possible faults. If the transmission fluid got really low, the transmission might have overheated with several consequences: burnt fluid; mechanical damage, case/part distortion, damage to hydraulic seals on...

Hi, thanks for writing in. This is likely related to the transmission control module which directs the transmission to shift up and down at specific points relative to engine RPMs. If you would like, consider having an expert automotive technician...

The fuel pump is going to be the most common cause of the loss of fuel pressure. I recommend having the fuel pump replaced. The fuel system and pressures should be completely checked prior to replacing the pump. I recommend...

I would not recommend using jumper cables as a means to connect your battery for a couple of reasons. First of all, it can be dangerous as it can create additional risk of sparks that would not otherwise happen when...

This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. The transmission control module has various sensors such...

Hello - I believe you have a problem with either your ignition switch (worn contacts) or the starter relay. Both of these components are capable of causing the electrical, "no start" issues you describe. I recommend a "no start" inspection...

Hi there: On a carburetor powered V-6 it is very likely that your choke or idle adjustment screw on the carb is dirty and simply needs to be cleaned. If you've never done this before on your vehicle, it might...

Hi there, thank for writing in about your 1997 Jaguar XJ6. It sounds like the alternator drive belt (accessory belt) is loose, glazed, or worn out, and should be replaced. A second possibility is that the belt tensioner has lost...

Hi, thanks for writing in. Almost certainly, what you were smelling was the clutch as you suspect. And, both the clutch and the limited slip mechanism in the differential may be damaged. The 2006 M6 Sequential Manual Gearbox ("automatic") is...

You will need to first verify spark from the coil. If you have spark the replace the spark plug or test the one in there to see if it sparks. If plug is firing then you have to check the...

Hello. It sounds like there may be a coolant leak somewhere that is hard to find. It would be a good idea to have the coolant system pressurized and inspected for leaks. By adding pressure to the coolant system, it...

The decreased engine power may be displayed for a variety of reasons, most likely there is a fuel issue or an engine misfire. In either case, the car's computer has put the vehicle into what we call "limp" mode. When...

Unless your repair involved replacement or modification of engine controls, such as the IAC valve or throttle position sensor, the instant you start the truck after replacing just a, or both, head gaskets, the engine should operate normally. If the...

A key number will be given to you with your set of keys. This number can be used to produce an authorized duplicate key. Write down the number and keep it somewhere safe, but outside of your vehicle. Tips You...

The fuel injectors in a V6 versus a 4 cylinder motor will look the same and may even fit, but the orifice size of the tips may be different. Injectors have different size flow rates of how much fuel they...

If it has a dipstick on it, then yes, you can just drop the pan, do all that stuff and fill it up and put the dipstick. A lot of them don't have dipsticks so make sure it has a...

It sounds like you may have a failing voltage regulator. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely...

The ignition coils are only meant to withstand a high electrical charge whereas the spark plugs can withstand that as well as the explosions within the combustion chamber. It is possible that you could have a small crack in your...

Hi there. When the oxygen sensors have readings that are similar to each other, it is an indication that the catalytic converter is not working as intended. If the voltage of the downstream oxygen sensor decreases, and begins to fluctuate...

You need to check the big vacuum line that connects to the intake manifold and goes to the brake booster and the pcv valve. The big T fitting at the intake gets a hole in it and causes the vacuum...

Yes. Never buy a Dodge Caravan. They have one of the worst transmissions out there. Those things are really bad. Now, if the line pressure is too high, that generally means that somewhere in the system there is a...

Hi there. The best way to diagnose any problems with the front end is to have a professional mechanic take a test drive. However, the symptoms you are describing are similar in many ways to worn out brake pads. It...

Fuel economy has many influences on it which can raise or lower the MPG. Are you calculating fuel economy per tank or off the trip computer? The trip computer is a constant average that might be resettable (see owner manual)....
