Hi Jimmie:
Fouling usually is coming from oil getting into that cylinder. Possible source will be oil rings or bad valve guide/seal.
Have you checked the compression?

Best to track down the source of the gas smell. Don't need engine fires. Run it a bit until you smell the gas. then shut it down and use your finger tips to feel for leaks at all of the gas line fittings, especially on the pressure side of the fuel pump. Look for places where dirt has collected, or where the area is cleaner than that surrounding it. Dust will collect on a small amount of gas, and will be washed away by a bigger leak.


I like your comment, " The harder you run it, the better it runs".
I've a Chevy big block in a dump truck. The instructions should say, "Run it like you hate it". It likes it.

Cheers,
Ted

Undefinedwhy I smell gas while driving car and car is running terrible


you could have a fuel leak in the system somewhere or you have excess fuel entering the combustion chamber and its not burning which will cause the smell of fuel and rough running. how long has it been since your car has been checked out by a mechanic.

Hi there:
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

My 1992 plymouth voyager 3.3sl started lossing pressure while driving and regain pressure afew mints later it will good then repeat. then one day i was driving and it stop driving it would ture over but...


sounds like fuel starvation.
did you run the car to the limit or run out recently?
you may have sucked up dirt from the bottom of the tank which is now blocking your fuel system.

if you crank over for a while and dont smell gas at the exhaust then it could be there is not fuel getting through.

remove the fuel line from the engine and see if fuel pumps out when you turn over engine.

just do a short turnover with pipe into a jar or some vessel to catch the gas.

if that is ok, replace pipe, also check fuel filter is not blocked, if one is fitted.

then there maybe a blockage in the carb or injectors remove spark plugs and crank over and see if you can see gas vapour.

warning do not use flame to see as this will cause explosion.




I hope this was useful.

2001 ford windstar lx too much gas odor ,changed spark plugs & wires, replaced all 4 oxigen sensors and catalytic converter.code detected says running too lean .


You have an Intake manifold leak or a leak in the fuelpressure regulator or fuel line. Most likely you need to check the Intake gasket with a water mist or Carb cleaner spray on the seams. Either one will produce a change in the RPM while the engine is running.

Also clear your computer, which I hope you did after changing all the parts you put on the van. When you get a Vacuum leak in the Intake, the fuel is not drawn into the cylinders properly and the ECU thinks the engine is running lean. The ECU orders more gas and the fuel regulator keeps dumping more gas in the engine.

Now you smell the excess gas, but the priority sensor overrides any secondary sensor saying its rich. The Evaporative Emissions system is flooded trying to reduce the fumes. In the end, you smell the excess gas.

Now both Autozone and Oreillys do free scans and their scanner may suggest more than what your scanner is showing. Check your Intake first, then scan it.
