When you say smell like exhaust, does it smell like rotten eggs (sulfur)? If so, could be catalytic converter clogged up.

Why do i smell fuel when i start my opel corsa bakkie 1.4 fumes coming from exhaust smell off fuel

Rick mixture or stuck choke. Get it to a garage and get it on an exhaust analyser. Will save you money in the long run with the saving in fuel. I presume fuel costs as crazy in Australia as they are in the UK.

Bad mpg on fiat stilo 1.8

the vehicle is running rich! Meaning there is to much fuel being pumped through the injectors or carb in the air fuel mixture that is pumped into the bore. If your car is running and you smell a strong fuel smell coming from the exhaust that is normally an indication of a rich mixture. This needs to be balanced which should improve your mpg. The other possibility is that the choke may be stuck open.

Engine stalls while driving down road,stalls while turning,and has lose of power. has heavy fuel smell out of exhaust.i was thinking fuel injector sticking. not giving any codes.

Technically it should have a code for the O2 sensors if nothing else. They should be reporting to the computer that the fuel mixture is too rich. Yes one of the injectors could be dumping fuel, or it could be a faulty fuel pressure regulator.

My car always smells like gas. The fuel filter was recently replaced.


Check the fuel cap. It is often responsible for the problem. ICheck for leaks at the fuel pump, charcoal canister and throttle body. If there is no leak, then the fuel smell may be given by a too rich mixture. In that case you often have more problems because of engine flooding. Try doing a code scanning and see if there is any code stored (e.g. rich mixture, misfire, or indications of other problem. If problem is rich mixture you will smell gas at the exhaust. If mixture is too rich, check the sensors in the air intake (MAF, IAT) and temp sensor. If the problem is none of the ones I mentioned, check the EGR system. Recirculated gas smells the similarly to liquid fuel.

The engine has to much gas running into it and is causing it to stall when put in idle and runs rough.

Seems that the fuel pressure regulator is bad, place a vise on the fuel return hose and if the car runs well replace the pressure regulator.
