If the check engine light is not flashing it is OK to drive the car with the particular code you have noted during the limited interval you are describing. A flashing check engine light would signify constant misfiring and you...
Hello there, thank you for asking about your 1993 Pontiac Grand Prix. The pump is self priming. If the red Oil Pressure Warning Light is not on, there is sufficient oil pressure. When engines are assembled, the oiling system is...
It depends on whose shop it is and what kind of work they do. That said, I've read an article the other day that 33 % of automatic transmission rebuilds done in the North America had to be done two...
It sounds like you have a misfire or low fuel pressure. You should have the computer checked for misfire or other codes and check fuel pressure to see which one is causing the problem. A mechanic like one from YourMechanic...
A few different faults can cause the vehicle to stall out like this. The most common would be the ignition switch, battery, fuel pump, fuel filter, or battery cable. The brakes will work without the engine on but they loose...
The gear shifter is held in park as a safety feature. If the brake pedal isn't fully depressed, the lock will not disengage and allow the hear shifter to move. On most gear shifters there are small holes that lead...
Brake pads can be accessed by unbolting the brake caliper from the torque plate. If you are installing new brake pads, though, such must be done at the same time that the brake rotors are re-surfaced or replaced and all...
Over time, the solenoids get weak. However, depending on temperature, the solenoid will be stronger or weaker. This is why it is intermittent. If you get the solenoid replaced then this should fix the problem. I recommend you have a...
The system uses a starter relay that is in the engine compartment fuse box. This relay is activated by the ignition switch through the clutch switch and engine control module. You may have a bad relay or problems with the...
The ABS and traction control are part of the same system. The electronic brake control module (EBCM) receives input from the wheel speed sensors, as well as other vehicle sensors. It then uses this information to apply the brakes and...
Hello - what a frustrating problem to solve! You may have provided a key clue to the solution, given that it requires another vehicle to jump start it to get it going again. This MAY mean that the increased starting...
Hi there. The problem with trying to diagnose this transmission fluid leak issue you have with the Hummer is that it's quite possible that the leak could be caused by multiple issues. Certainly a loose transmission fluid tube or damaged...

What you are describing is likely an electrical fault involving the safety shift interlock. This problem can be diagnosed and resolved on a mobile basis, right at your location, if you request a transmission shift interlock diagnostic/repair. To temporarily resolve...
Hello. If the alternator is testing good then you probably have a failure in the control circuit for the alternator. This can be a fuse, wiring or it can be the computer. I usually need to test the circuit with...
Hello. It sounds like it is possible that your transmission may be starting to fail. If your car is rolling when it is in park, it is not staying in the parking gear. This indicates that there may be an...
Because you left the car running but it died anyways, this tells me that this is not the battery at fault. The most likely culprit is the alternator. Many people are not aware, but testing an alternator is really easy....
It sounds like you may have a dirty or failing idle air control valve causing your engine idle to fluctuate. The idle air control valve is a small valve on the engine's intake system that reads the air intake as...
Hi and thank you for writing in. Most likely what is happening here is that, by over filling the gas tank, you allowed gas to enter into the gas tank breather tube. As you start driving fuel is being drawn...
This may be related to a faulty blower motor control module or resistor. The blower motor resistor controls the various speeds and functions of the blower motor once it is turned on. I would recommend having an expert from YourMechanic...
If the check engine light is on indicating that the O2 senor needs to be replaced, this could explain the shaking and stalling depending on the functionality of the O2 sensor. As you may know the oxygen sensors which are...
