The most common causes are a faulty injector or fuel pressure regulator.
If one of the injectors is not closing, it will allow liquid gas to flow into the cylinder and past the rings.
If the regulator fails, it will allow liquid gas into the intake.

The sending unit in the fuel tank most likelt went bad. It is probably a coincidence that it happened at the same time as the oil change.

SOURCE: wife,s 97 buick skylark, 2.4 L., leaking water. need help!!!

I had the same problem a month ago. I thought it was the thermostat, which sits inside the lower water feed tube that runs from the radiator, under the car and up between the engine and trans axle to the thermostat housing and water-inlet housing attached to the water pump. I replaced it and it kept leaking. So I got under the car with a mirror and a light and found that it was leaking from a weep hole in the water pump. This happens when the water pump seal is bad. to replace the water pump you nearly have to take apart the back of the engine and the timing chain cover. The waterpump is mounted at the bottom of the back of the engine and is turned by the timimng chain. It took me two days to fix, and it was not easy. There are a couple of sites that have info, which helped me. It's about a $600 - $900 job if you take it to a repair shop.

SOURCE: MY 1996 buick skylark olympic edition leaks water

Taste the water and if it is sweet it is coolant leaking from the heater core. If it does not taste sweet it is a leak somewhere else. What you suspect is very possible. Start by making sure the drain hose is clear an not clogged. Then check the window gasket. A water hose left running on the window slightly will tell you where the leak is coming from.

The actual cause may vary. If I remember correctly a bad oil pressure switch might cause the ets to turn off. Or it might be a defective oil pump. Either way, you will need a qualified technician troubleshoot the cause.

Cant find Low pressure AC port


Did you check the acumulator? There is a port on it, that is the low side port. Keep in mind that if you have to recharge the system it is because other parts need service (leak in the syst) and whatever refrigerant you put in it will leak out again. The system may work temporarily or may work inefficiently. Also may sure that there is oil in syst.
