I assume your question about "cleaning" your converter, because, you think it's dirty? Lost power? more than likely blocked than dirty. That being the case, you can't clean or unblock a converter. Time for a replacement unit. If your handy with a welder, have a go? If not, your local exhaust shop should steer you in the right direction as far as matching your unit, ie substructure, porcelan or metal and std's obd3 etc... cheers

Where should I place a hole in the clogged catalytic converter on my 1999 Dodge Neon onto clean it out?


Most cat converter products I know of are poured into the fuel tank. The car is then driven until empty. These preps won't fix a dead converter, but can boost one that is just dirty inside.

Do you have a different sort?

All this all fails, cheaper generic converters are available from Autozone and similar places

I would make sure your fuel filter is clean and have your catalytic converter checked to make sure it is not clogged up.

Trouble code po430 what does this mean? also car sputters or hesitates when drivng runs smooth at idle ?


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.

I need to replace my mazda mpv catalytic


Ok the fastest way to solve weather it is the cats in the exhaust system is to take it too a exhaust specialist and ask them to do a exhaust pressure test. They should have all the pressure drop data there and can tell you if there is to much restriction in the exhaust, if there is to much chances are they will be the cats, usually the front one. Yep your dad is correct with his theory, but excessive overfuelling will also cause the cats to build up excess heat and start to melt, or fall apart. So get a good service when your able too, plugs/filters and oils. Yep your firing order is correct.

Cut u cut the catalytic converters off the manifold and just replace the catalytic converter by cutting and welding it back together


You can cut them off and weld them back on. You don't have to buy a new exhaust system if that's what you're referring to. Here the ford dealer wanted $2000 to replace mine, but we had aftermarkets put on at a local shop for $300.

How to Clean a Catalytic Converter


When light is on for Catalytic covert-er usually mean that Bank1 sensor #2 is bad or going bad.There is only one catalytic converter on this vehicle. The only way you can purge the converter there is NO real way of cleaning it but you can use EMISSION CURE its sold at auto parts stores like Auto-Zone etc. This EMISSION CURE you pour it in you gas tank and it will help removed some carbon and debris from exhaust system to clean up emission. Good Luck and thanks for using FIX YA.
