Car is running rich...

[Edmond]

pulled the codes and it's running rich.

Yes, I do occassionally smell gas.

Could the injectors be stuck open?

O2 sensor was replaced last year.

What about that little emissions canister by the left headlight? Can that cause me to run rich?

If it is the injectors, is it economically wiser to replace or service them?

Wow, I never saw this one Ed. Now I sound stupid for saying what I did in the other thread. (about the charcoal cannister )

If an injector(s) sticks open, it can pour fuel into the engine when you shut it off, sending fuel into the crankcase. Is your oil over full? I had a friend with a 93 Blazer that that happened to, and it cost him an engine.

Beware!

Ken,

The car is also having trouble upshifting when I let off the gas to slow down and then step back on the gas to speed up. It kind of shakes, kind of like the fuel isn't getting there or it's getting too much fuel.

Would the charcoal canister cause the upshift problem?

 

[Ken]

No, but the charcoal cannister does have vacuum lines, and the transmission operates with some vacuum lines... Hmmm, he said as he scratched his head... :confused

How do I check to see if my canister has failed? What is the techinical name for this canister? How much would a canister set me back?

Questions, questions, questions... :L
From SmogTips.com:

Charcoal Canister (Evaporation Control System)

This system is designed to prevent the release of gasoline vapors into the atmosphere. Although EVAP systems vary they all contain one similar component. This component is the Charcoal Canister. The canister is responsible for storing gasoline vapors from the vehicle's fuel tank/s and carburetor float bowl (if applicable) until the engine is ready to burn them through the combustion process.

The charcoal canister is usually located in one of the far corners of the engine compartment. It is normally a black container filled with charcoal pellets that absorb fuel vapors. Not all charcoal canisters however are located in the engine compartment. Some vehicles manufactures have mounted their canisters closer to the vehicle's gas tanks in-order to maximize space efficiency. See your vehicle's "Underhood Emissions Information" label or a local certified repair shop for location information. Find this component and insure it is connected properly.

Here's some good reading from a Lotus site, Fuel Tank venting.

The price? A lot? :confused

Flooded charcoal canister or a leaky purge valve;
Defective mass airflow (MAF) sensor, manifold absolute pressure (MAP) sensor; or
Defective throttle position sensor;
Engine remaining in open loop by thermostat stuck open or faulty coolant sensor.
