An overcharge of either refrigerant oil or refrigerant can cause excessive system pressures. If the wrong refrigerant oil is installed that might contribute to excessive pressure. Check low side pressure. If low side pressure is too low, while high side...
The alignment issues that you are referring to would have to be looked at first hand as there are mechanical and electrical issues involved. It might be fine but it has to be looked at up close. As far as...
With the fuel pressure low by 10 psi and leaking down indicates the pump in the tank or the pressure regulator is leaking down pressure. You will need to isolate the pump by blocking return line to see if pressure...
Hello. It sounds like you have an internal leak in the injection unit. This is very common. The poppet valves stick and cause this to occur. If the pump is isolated and holds pressure then it is the injection unit....
ABS is the acronym for Anti Lock Braking System. It's a safety feature that uses computer control to prevent individual wheels from locking up under hard braking. A wheel that is sliding will not steer, so ABS fixes the old...
It sounds like you may have an alarm of some kind going off in the vehicle, which may indicate something may be wrong such as low fuel or potentially a check engine light coming on. Generally, the check engine light...
Hello, thank you for writing in. Considering the age of the vehicle, the transmission may need to be serviced. This would include a fluid and filter change. During that process it can be inspected for signs of wear and obvious...
It is possible that the misfiring cylinders could have low compression. I would recommend havong a compression test done on the engine to check for bad piston rings and valve seats. If there is low compression, the engine will not...
Hi Nicholas. Generally speaking, when you're able to turn the key and the starter engages, but will not ignite the engine, it will be related to a fuel or ignition system component - or combination of them. Some common parts...
Hello, thank you for writing in. You may want to start by making sure your air intake and throttle body are all clean and working well. Then, perform a compression test to make sure the engine itself is not your...
Hi there. If your gas light was on prior to putting fuel inside your Blazer, it's possible (yet unlikely) that the fuel sensor in the tank may have been damaged if it was really low on gasoline. Sometimes a faulty...
In the majority of vehicles, engine idle speed is controlled by an idle control valve (ICV). The ICV valve can fail or a faulty or blown fuse in other electronically controlled systems can cause the IAC motor to malfunction, leading...
If the transmission won't shift to second gear, possibilities range from a leaking clutch piston to faults in the valve body. There is a possibility of an issue with external electronic controls, too (all of that is covered in the...
If you suspect the wiring is shorting out and there is a chance of a fire then i recommend you disconnect the battery until you have a mechanic like one from YourMechanic check it out for you. If you have...
On a marginal ignition system, condensation on ignition system wires and components could cause voltage to bleed away just enough to make starting difficult during the humid conditions you describe. If the problem persists, the recommended service is a no...
What you are describing is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer...
I do believe that changing the vin back to the vin from the engine is likely to solve this problem. If not, a reflash is likely to solve the problem in the event that changing the vin back does not...
What you are describing sounds like you may have a clogged or damaged catalytic converter. The catalytic converter converts toxic exhaust gases into less harmful pollutants that are suitable to be expelled into the atmosphere. When the catalytic converter is...
