Question about 2000 Toyota Corolla
I am at my wits end gentleman, i drive the car mentioned above. I have had problems with the vehicle before but this is taking the cake.
My car is burning to rich i can smell the fumes. The car is also not performing as it use to. I also am experiencing the car is having difficulty in idling. I have done a diagnostic test myself and the fault codes was 22 and 41. I need the car to at its ultimate performance potential.
The fault codes for your vehicle are probably make specific. Can you list what you OBD tool specified the problem to be?
In most rich running instances the fix is attributed to:
Dirty Mass air flow sensor (clean with brake cleaner as it does not leave residue like carb cleaner does)
Dirty O2 sensor (replace with a generic for under $30 if you can do the labor yourself)
Bad spark plugs or oil around ignition coils. You may way to pull and test each coil with a volt meter. You are looking for between 100 - 150 ohms to be within spec for this car. The ignition coils are what we used to call ignition wires or spark plug wires but now run without a distributor to be more efficient.

The engine and automatic transmission (If equipped) in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
