Can a check engine light with and error code of EGR cause black soot in the tailpipe of a 2005 dodge grand caravan???


Hi. The black soot is that your engine is running too rich. I would have checked out the O2 sensor. The O2 sensor tells the computer how much gas is needed to run your car. If the sensor is malfunctioning or dead the computer will make the engine run with more gas (rich) Go to your mechanic and have him run the code scanner. I would also clean out the EGR valve which you can do yourself. Good luck

I have Hyndia Tucson 2006 Deisel. I have a problem in it. This problem is smoke heavily (Black) and there is no intention of any force during press the accelerator.


mean there might be fuel leaking into the engine or the air to deisel ratio is and not atomised correctly. the main causes are normally is the air filter that isnt allowing air into the engine. Fuel filter can also be at fault not allowing enough fuel in or allowing to much in the engine sometimes. This causes the chamber to burn it out. Fuel injector if fualty could allow to much fuel or not enough. My personal suggestion would be to run fuel injector cleaner first, then change the air filter. If that doesn't fix it change the fuel filter. I would go the cheapest route first. Is is prolly something simple

98 gm blazer has black soot from muffler giving code insufficiant switching o2 sensor bank 1 and 2 any ideas ?


Your Jimmy is running rich, air fuel ratio is not correct. Start with cleaning your MAF sensor, a dirty MAF sensor will cause your engine to run rich or lean, other causes would be a faulty fuel pressure regulator. Start with the simple and to common and try cleaning your MAF sensor, you can pick up a can of MAF sensor cleaner at most auto parts store like Auto Zone or Part Source.
Also make sure your engine is running at the proper operation temperature 190", cold running engine will cause the ECM to run your engine rich. Causing the back soot and fouling up your spark plugs and intake ports with carbon.
The ECM was programed to recognize the 4.3 vortec to run at 190" and anything cooler will cause it to run rich and poor on economy.
Thank you for using fixya and good luck.

Vehicle smells like gas both inside and out of car after engine is off. Check Engine light is on but no noted deficiences noticed, all fluid levels good. what could be the problem?


If your check engine light is on when the car is running, then that means there is probably a trouble code stored in your vehicles computer. With a code reader, you can find out what the code is. That will direct you to the problem. You can post your code here and we will tell you what it means.
Regarding the 'gas' smell, first check to see if your car is running 'rich'. You can rub your finger inside the tailpipe and see if there is a lot of black soot there, which would indicate its running too rich (too high of a fuel to air mixture). If this is inconclusive to you, remove the spark plugs and check if they are with black soot on them where the pin is. This will tell you how the engine is running in terms of fuel mixture. If they are black, then you have found the problem (fuel injection problem or Oxygen sensor, most likely). The trouble code might also point to this. Other than that, sometimes an exhaust leak can cause fumes to leak up into the car when running. My car had the gas smell problem and it was both a hole in the exhaust under the car and an overly rich fuel mixture. I had black soot inside the tailpipe and black sooty spark plugs and the final problem ended up being a bad oxygen sensor (located on the intake manifold), that was sending an improper signal to the vehicle's computer, thus the reason for the problem.

Car will start but dies when pressing the gas pedal


It sounds like you have an issue with something in your air/fuel mixture electronics. This could be something in your throttle body, mas air flow sensor, or even an oxygen sensor. When your car is idling the air/fuel mixture is acceptable for the engine to run. When you press on the gas either too much gas is dumped in the engine or too little. If you look at your exhaust pipe you may notice a heavy built up of black soot. This would indicate that your vehicle is running extremely rich (too much gas), if your exhaust is very white then your vehicle is running lean (too little gas). The smell of the exhaust can also tell you something about how the engine is running. If it smells sweet it is running rich. I hope this helps and please don't forget to rate me.

90 camaro running rich


You may want to install an adjustable pressure regulator to provide what the engine needs, not what the computer thinks it wants...Check with Holley, Moroso and Edelbrock to see if they have something that will help. Of course check the management controls to make sure they are working, but except for the MAP, I would expect a lean not rich condition from those items. If you are using one, check the mass air flow sensor when dirty inside they can cause problems.
Good luck (always said someone should build a 440 mag "69 charger with electronic injection...want to see quick???
