I have a 2000 ford focus that smells like rotten eggs. It runs great. Where could the smell be coming from?


You have ignition cylinder misfires or a rich fuel
condition, that most likely ruined the exhaust converter
That is what you smell, a converter that should operate
900 to 1300 degrees
Yours got to 1600 & melted down
Now you need to solve ALL ENGINE ISSUES FIRST
then replace the converter & oxygen sensors

Was running great then it just would not start and when it did it started idling fast now the exaust will glow red


if engine is running without missfire check catyletic converter for plugging also very rich running will cause exhaust to glow but will cause alot of black smoke from tail pipe I dont reccomend driving vehicle till exhaust or rich running is fixed can lead to engine failure

Runs great but will quit running , smell gas also


Sound like a rich by a long way; are you check if have smoke in exhaust? Black smoke is fuel, blue smoke is oil.

Also, your injectors are to big and is running rich.

Engine miss ,running rich ,-rottten egg smell from exhaust ,new plugs and wires,68000 miles 4.3 motor


It sounds like it may be your O2 sensor because if it is not working properly, the engine cannot determine how much fuel to ingest which would cause rough idling.
  • sometimes a bad 02 sensor causes a fuel smell from the exhaust, or you can just remove and check the sensor. if its really black "like charcoal" you might wana get it changed, also checked the wires on it and make sure they're not torn or anything. have scanned to find problem code if check engine light is on. good luck!!

Black smoke when i start engine, very rough idle.


sounds like possible a sensor went bad or is loosly connected. O2 sensor??? Also check the air filter. Sounds like whatever it is, is making the truck run rich----that would be the black smoke.


Hope this helps

if smell rich but you have a lean code then most likelly the 02 sensor is not working good, also a stuck egr will give you that problem
