Question about 1991 Cadillac Eldorado

1 Answer

I had my old catalytic converter turn red and was told by a work mechanic that I needed a new one. So I had a new one professionally installed. I have changed the spark plugs, spark plug wires. PCV valve, 2 02 oxygen sensors, and the converter is still turning red.Also I have had 2 dignostic test done on my 1991 cadillac eldorado, but even the new converter is still turning red. What can I do as I am spending money and no results. I need to know what I can do, to stop this. Thanks

Engine is running rich. Some reasons might be MAF sensor or computer. Is the engine light still on, or what are the codes you got from the previous scans?

You do not mean cranking,the starter turns
over the motor,that is cranking, is it not

You mean it doesn't start,that is a NO Start Condition

Lets use common sense here

You didn't need to ask any questions here
because the exhaust converter gets red hot & the
car is not only unuseable but overheats

Your looking at at least $1000.00 to diagnose &
resolve many problems

The converter is 14 years old & if it wasn't red hot,
it is time to replace it

It is hot for several reasons,you did not say what motor is in there

The timing is most likely an issue

Also you can not replace the converter until you replace
the spark plugs,get rid of any cylinder misfires,rich fuel conditions,fix fuel trim,& such, all of which along with timing
& I mean serious mechanical repairs, have attributed to ruining
the converter,oxygen sensors,all of them, from the heat
& the list goes on.

Lot to have checked out & you can't do it in your driveway
with no experience & no professional test equipment

If your mechanic is right about catalytic converter at fault then you can ask him to just remove those for a while and check if your car works fine. Catalytic converter are there just to reduce pollution and I don't recommend to drive without them but for checking you can do that for a while.

I bought a 2003 cat converter from NAPA(Part No.16403). My mechanic was unable to put the old heat shield back on. I am again seeing the "check engine soon" message on my instrument panel. ...


A 2003 vehicle probably did not need a new converter. Cat converters have to be run for years before they clog up. Depending on what kind of vehicle this is, you may have a post catalytic oxygen sensor problem. Also, depending on the vehicle, you can not just replace the converter with any old converter. Many vehicles require an OEM replacement converter in order for the sensors to work properly and these are expensive. Kansas City Converters (available online) sells replacement converters for a fraction of the price that will work with post catalytic sensors and not cause the check engine light to come on.

New catalytic converter gets red hot


clogged , check the rest of your exhaust after cat to see if it gets hot

you can buy a no contact thermometer for less than $55.00

Engine using oil. No sign of leaking. Catalytic converter replaced 13 months ago, now needs replaced. Told need new engine. What is causing the catalylic converter to plug?


Was a leak down test performed on the motor?This will determine if the oil loss is due to bad rings or a head gasket.A head gasket can be repaired,rings will require an overhaul or new motor.Have checked the coolant for oil contamination?

Starting w the timing belt, It must be removed to replace the water pump, there's shouldn't be any addtl labor involved to install a new one. Since the fuel is leaking & the converter is overheating you are asking for BIG TROUBLE if u don't replace them both. Fuel & converters DONT MIX!
