emissions failure

High carbon failure on a 92 cutlass supreme. Easiest cheapest way to fix? Maybe without an expensive diagnostic test?:2cents:

Welcome to AF. High HC's?

Too much carbon monoxide making it through the converter. A new one of those is out of the question. Looking for a quicker cheaper fix to get passed the test. Heard 44k might help.

Most likely a cheap aftermarket cat replacement is going to be the only way here. Make sure the car is good and warmed up before the test, also.

I was afraid of that. Thanks for the help

Change your spark plugs, air filter, fuel filter, and clean the throttle body.
Then, fill up your gas tank and put some fuel system cleaner in there.

Short of that, you'll have to change the cat.

Yes sir you hit it dead on 95supreme, i had the injectors blown out too, made a huge difference. Thanks for the help guys.
