Check the vent hose at the vapor canister. I do not know the location on your car. If the hose comes off, you will get gas odors

SOURCE: engine light on, all levels

Try disconnecting your battery for 15 minutes...then re-connect. This will reset all of the solenoids to factory specs...and will clear the engine light. If the engine light comes back on then you should try to get diagnosed at a free diagnosis service may need to call a few. Hope this helps.

2008 Winnebago. We get a sewer smell if we roll down a window while driving.

A motor home will pull sewer gas from the holding tank if you cause a vacuum in the vehicle.This will happen to all units but will be more pronounced with a toilet with a bad seal on the flush valve.
Keep the door closed for the bathroom when driving and use the dash vents for outside air with all the windows closed as this will pressurize the RV with air and not allow sewer gases into the unit.

Sounds like a solenoid switch on your starter is gone. Probably need a new one. Sometimes if your starter is jammed you can tap the starter with a hammer but not too hard as to bust something.

I bought a 2008 Lucerne CXS recently and have had nothing but problems in regard to mpg. GM replaced # 5 fuel injector; however, the car still has very poor mpg (13 per gallon) and the exhaust smell is...

does it smell like sulpher or rotten eggs? if so your catalytic converter is stopping up. if you're not in a state that requires emissions testing, have it removed.

Po441 emissions code for a 2000 Avalon - just wondering some possibilities on what it might be and what it will cost.

This indicates that a part of the EVAP control system is no longer functioning correctly.

FIRST, call the local Toyota dealer, tell them the error and your mileage. It MAY be covered under warranty as part of the emissions system, which many manufacturers have extended warranty programs on at no cost to you.

A code P0441 could mean one or more of the following has happened:
  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
  • Replace purge Solenoid
  • Replace vacuum switch
  • Repair restriction in Evap line or canister or soleniod
  • Repair resistance in purge connector
  • Replace PCM
