You say you 'changed the spark pug' (singular), did you only change one? When one fails, the rest are going to follow.
Your O2 Sensor and O2 Heater are probably the same sensor that is failing. When they fail and are running lean, they dump fuel and that soots up the Catalytic Converter, so there is your other code. Replace the sensor that is causing the issue and run some Extreme Clean Catalytic Converter Cleaner in the fuel. You might need two treatments.
Got it scanned and it's P0420: Catalyst efficiency below thresholdbank 1. They said it could be a bad catalytic converter or oxygen sensor. I borrowed a scanner and tried to measure the oxygen sensor readings over time.Sep 8, 2011

you have major problems is it worth fixing???,its gonna be quite a bit
Have there been any driveability or performance issues with the vehicle, have there been any recent repairs or tune-up work performed, if so was the check engine light reset and were the codes recorded on previous repair orders.
Do not rely on scan tool data alone. In most applications, the customer will have the check engine light reset prior to repair. If the original cause of converter failure is intermittent, only the catalyst failure code may show up
The P0420 means Catalyst System Efficiency Below Threshold (Bank 1), and the P0430 means Catalyst System Efficiency Below Threshold (Bank 2). __________________ ECU unlock immobilizer tool
Diagnostic code produces P0420 catalyst system efficiency below threshold-Bank 1. Probable causes are listed as follows: 1-air leak in exhaust before rear 02 sensor, 3-Fuel system fault, 4-faulty catalytic converter.
Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter's
emissions efficiency has fallen below the minimum allowable limit. This
threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on
or near the outlet of the Catalytic Converter.
Symptoms
* Check Engine Light will illuminate
* In many cases, no abnormal symptoms may be noticed
Common Problems That Trigger the P0422 Code
* Defective Catalytic Converter
* Engine misfires have damaged the Catalytic Converter
* Internal engine damage resulting in high oil consumption and/or a leaking Head gasket has damaged the Catalytic Converter
Common Misdiagnoses
* Oxygen Sensors are replaced when the real problem is a damaged Catalyst
* Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
* Catalyst is replaced when a misfiring engine is the real problem

Hi, this code represents a Catalyst System Efficiency Below Threshold
(Bank 1). and the repair, considering that it will be repaired by the dealership, seems to be in the normal cost range. The labor is what usually inflates the price when dealing with catalytic replacements.
You could probably get a better deal by taking it to a non dealership type of repair shop. This may cut at least 200 dollars of the original dealership quote.
i have a 2001 venture van and the same code came up .Is it a good idea to get it done as soon as possible?
Do you have a PO420 code?
