Hi there - it is possible that your "popping out of gear" problem is worn shifter linkage, bad transmission or shifter mount, or worn shift detents in the shift selector shafts. These are (relatively) easily checked without dropping the transmission....
Crankshaft damage can occur for a few reasons. One can be from the engine running hot or overheating. Proper cooling system operation is important. Lubrication is another. If the oil level is run low or oil changes not being done...
It is possible that you may have a leak somewhere in the AC system. However it is normal that every few years your air conditioning refrigerant will need to be serviced, as the refrigerant is a gas and does slowly...
Be sure there is adequate fuel in the fuel tank and that the fuel is not old. Check for adequate fuel pressure, injector operation, and a spark at the spark plugs. Basically, if the starter motor is turning the engine...
Hi there. I would recommend buying the stock vehicle, as the one with an engine replacement can have difficulty passing emissions. This may why it's registered as a "hot rod" in your state. If your vehicle passes emissions, you should...
The answer to that depends on which type of rearview mirror you have. If you’re thinking of the rearview mirrors we’ve been using for decades, with the little tab on the bottom that flips up or down, let’s talk about...
If the AC is only blowing hot air then most of the time it is because the AC compressor is not turning on. The compressor will not turn on for a number of reasons, but the most common is low...
Hi there. The fuel pump could have failed due to crystallization of the fuel if there is too much water in the fuel). I recommend putting a treatment of water separator in the fuel tank and let it sit for...
The throttle body is the part that allows and controls the entry of air into the engine. Throttle bodies have a butterfly valve inside them that opens when the gas pedal is pressed and closes when it is released. Your...
Hello. From what you describe, it sounds like there may be some sort of issue with the clutch pressure / cycling switch. These switches are responsible for activating the compressor when they detect that the pressure is at or temperature...
Brake lights that come on intermittently are likely caused by a faulty or misadjusted brake switch. The problem could also be caused by a short in the brake light wiring. A trained technician, like one from YourMechanic, will be able...
Hi there - while the basic engines have stayed relatively similar (3.3l or 3.8l), and the basic transmission is the same (41TE), engine and transmission management has changed considerably. Staying with the same engine (EGA/EGH) may work as long as...
An engine failure is definitely not good news. Engine failures can be caused by numerous things (e.g. low oil pressure, contaminants in the intake, etc.). Thankfully the 2007 Optima is covered by Kia’s 10 year, 100,000 mile power train warranty....
The power steering on this vehicle has an electrical power steering pump that supplies pressure to the system and communicates to the computer system on the vehicle for any problems. If you say you are seeing a power steering light...
Your description suggests you may have a bad grounding problem, a short somewhere, or potentially a failing voltage regulator. The voltage regulator regulates the power charged to the battery by the alternator to ensure that the battery is not over...
Hi there. It seems that the EGR (Exhaust Gas Recirculation) Valve is stuck and not allowing the engine to run good causing the engine to hesitate, especially when shifting. Take the EGR off and clean it. Then put it back...
Hi there: Typically a dashboard warning light is an indication that the ECU has detected a fault of some type of an electrical or mechanical component. If the electric power steering light is illuminated, it's likely that one of the...
Hi. If the engine will turn over and try to start, then it may be a problem with fuel pressure or one of the engine sensors. It is common for the fuel pump to fail as well as the crank...
From what you've described, you may have a bad crankshaft sensor. You'll know if this is the case once you run a scan test to get sensor data. The sensor may not be sending a crankshaft signal to the computer....
Hello. This noise can come from a few different things. You are right that most of the time it is caused by a failing or loose belt. If the belt is loose then it may be the tensioner that is...
