Burns gas rapidly; exhaust emissions has pungent smell and is dark brown/black; idles rough at standstill whilst in gear; shuts off at times; fuel injectors were cleaned. One mechanic suggested throttle body is bad-maybe, maybe not. Help.

Try changing the engine coolant temperature sensor, and has the check engine light ever came on and stayed on? Durring this problem. If so have the on board computer scanned. Good Luck. From Ernie @ RedDeer, Alberta, Canada.

What is EGR


It's the Exhaust Gas Recirculation system.

A motorised valve in the exhaust system opens & closes when required to allow some exhaust gas back into the inlet so it' goes back through the engine - any remaining fuel is burnt & emissions are reduced.

These can be prone to fouling with carbon & residue which causes reduced valve movement or complete jamming - it can be intermittent & can result in a variety of issues, poor starting, rough idle, cutting out, lack of power........

What would cause 93 chevy c1500 rough idle smells of excess gas at exhaust


Does the truck seem fine when you first start it & then acts up when it reaches operating temp?
That would lead me to look at my oxygen sensor, a bad sensor can cause the truck to run "rich" which would explain the fuel smell in the exhaust.

Rough idle and smells like gas when driven


When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Hi, 2002 dodge Dakota, 4.7l, got home from work and shut off. 10 minutes later, went to start and made a noise like a car makes when you try and start car when it is already started, then idle was rough,...


The chain could jump a tooth or two, but normally a chain or gear breaks. You could pull the spark plugs and check compression to find out.
It sounds like one or two injectors may have failed allowing liquid gas to flow into the cylinders.

1992 es300 blue smoke from exhaust


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. So best bet is to have a local repair shop inspect for internal oil leakage.

Cold start-extremely rough idle-Shakes,smell fuel


Black smoke means buring rich. Have the vehicle's ECU scanned for codes and do the repair the codes describe. I'm gonna take a stab in the dark and say Mass Air Flow Sensor.(MAF)

Own a 2001 nissan sentra check egine light is on, car will start but runs very rough and smell of fuel. It will idle roughly in park, but once in gear no power


sounds like engine rebuild time and you need to have the transmition rebuilt too. i hope this helps. if you want to try flush the engine and fuel lines with ethenol. but if you flush the engine you will need to empty the fuel tank first. after you flush the engine full with fuel and run at idol for a couple of minutes. treat the fuel. this should help the engine to run properly whilst you wait to rebuild it. give it a service too. when you flush the engine too white smoke should be emitted from the exhaust or if you have a catilitic converter the white smoke should be reduced. hope this helps.

99 olds silhouette check engine light blinks.Engine is running rough and the smell of unburnt gas is coming from the exhaust.Also noticed a burning smell coming from between the engine and firewall.


the cat converter is overheating because the engine is misfiring, get it to a repair shop ASAP, I would tow it, but converter damage has already been done.
