Hello guys. I purchased a 92 sc300 last weekend. I bought it very cheap knowing the car had some sort of problem. THe reason I got it so cheap was because the dealership told the previous owner, the prob was because it needed the head rebuilt. ANyhow. I have driven the car for about 250 miles problem free. I had made the comment on how well the car ran, and then it happened. JUst started running rough. I pull off kill the car start it up and then it was fine. A minute later the same thing. It is just dumping fuel in there. It smells as if im pouring fuel on the ground. It is also puffing white smoke. It even gets to the point where I leave a trail of smoke if I idle for a period and take off... ANyhow any ideas?

 

Can you hear your fuel pump running when you start your car?

Check your MAF is plugged in and run the OBD.

 

Yeah, It's running. After further review I think its the head gasket. MAybee coolant leaking into one of the cylinders and that reason giving me the raw fuel smell since the cylinder is being extinguished. Also when the car was shut off the return radiator hose collapsed. I changed the oil and it was in tip top shape. I'm going to have the cooling system pressure tested to see if infact theres a leak somewhere, just before I start to remove the head...

 

THe maf was the first thing we checked. The only thing that keeps me from thinking that the fuel is dumping in from poor metering is the simple fact that the smoke isn't black. It's almost pure white. If you sniff the exhaust you can smell raw fuel.. ANd the whole hose collapsing thing.
