Some symptoms of a bad catalytic converter on a 1994 Lumina are engine stalling, engine backfiring, no start of engine, and poor power pick up. If the catalytic converter has rust holes, the vehicle will also be very loud when running.
yes, its a dealer only item in California
Low catalytic converter efficiency.
A Platinum and palladium coated ceramic matrix.
yes keep o2 senser installed then no prop
It is either clogged and needs replacing or you have one or more cylinders that is not firing properly and unburnt fuel is being ignited in the converter. On an 18 year old car I would suspect the converter is clogged.
Clean the MAF sensor with CRC MAF cleaner. Check the airfilter. Check for a clogged catalytic converter.
Hard starting, loss of power, excess fuel consumption, check engine light, and a blowing sound under heavy acceleration.
Did you replace the thermostat, and check the water pump? Does the cooling fan operate as it should? A plugged catalytic converter can cause overheating. If above items check out OK you need to check for leaking head gasket.
it is located at the top off the brake pedal with the brake switch. just had to replace one.
