SOURCE: trouble code po430 what does this mean? also car

This code means the Catalytic converter on bank 2 is not working efficiently. If your car is acting up with hesitation the Catalytic may be getting fouled by the way the engine is running. There may be another Code to read for the problem that caused the Catalytic converter to foul.

You have between 25 and 35 Startups before a Code is erased. Consider the Code 430 as the last Code recorded and the other Codes were beyond the 25 to 35 Startup limit.

You have several choices. (Autozone and Oreillys give free scans) There are fuel additives which claim to clean the fuel system and Catalytic converters. You can have the car put on a better machine at a Dealer to find the cause of the hesitation. BUT tell them you want the type of test for cylinder balance and timing issues, not just Code numbers.

Once you restore the engine to Specs, the Catalytic converter may clean itself over time.

02 chevy 4.3 from idle hesitates under acceleration but quikly smooths out

The engine and transmission in this cars 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 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 THE DIAGNOSIS & TESTING IS COMPLETED.

Check engine light is on. Has a miss when under load. At idle it is smooth.

have the fault code checked that is stored along with the check engine light, the code will tell u which cylinder is misfiring, Kragen and Autozone both do this OBD2 electronic engine control fault code test for free, just tell them your CEL is on and ask them to test it.
