I have stumbled upon this great forum in search of the answers to a recent problem I am having with my 92 LS. I've had it for more than a year and all have been perfectly fine until yesterday. When i tried to start it, it wouldn't stay on. There is a knocking noise from under the hood. It felt as if the engine is drowning and just struggling to stay on. After struggling for a minute, it goes off. There were alot of water coming out of the exhaust. After a lot of frustration, i started it while pressing down the gas pedal and the tachometer got to 3. It started this time and stayed on and ran as normal. This was after a more water has come out of the exhaust. I thought all is fine that maybe someone intentionally put some water into the exhaust. I drove the car home it it was all back to normal. Today i tried to start it again and its giving me exactly the same problem with water coming out of the exhaust. And there was a lot of white smoke when starting it and i can smell petrol. Guys, any reply to point me to the right direction would be greatly appreciated. I don't have a clue what might be wrong.
