Do I need a new Catalytic Converter ?? Sign In

1994 Plymouth Voyager
Odometer: 216000 Kilometers
Engine: 3L , 6 cylinder
(engine rebuilt about 4 years ago)

I live in Toronto, Canada where we need an emission test every 2 years.
I did the emission test last year, and passed, but not by much. My mechanic said I would need to change my catalytic converter to pass the test next year. I can afford to change it now, but need a second opinion as to whether changing the catalytic will improve my results compared to last year. Here are the results from last year:

ASM 2525/CURB IDLE TAILPIPE EMISSIONS RESULTS:

---------ASM 2525 TEST====================== CURB IDLE TEST
------------Limit------ Reading------ Result========== Limit-------- Reading-------- Result
HC ppm ---0054 ------0046 ---------PASS=========== 0200------- 0038----------- PASS
CO % ------00.30 -----00.03--------- PASS========== 01.00--------00.01---------- PASS
NO ppm---- 757------- 583----------- PASS========== N/A--------- N/A------------ N/A
-------------RPM ------1988 ----------VALID ==========RPM ------ --0781 -----------VALID
-------------Dilution ---14,73 ---------VALID ==========Dilution----- 14,21---------- VALID

Can anyone interpret these results??
Any help will be greatly appreciated.

Those are passing results. What's there to interpret?

I honestly wouldn't worry about it until it doesn't pass.

The DriveClean program has changed as of JAN 2013 in ontario. Now the test is completely OBD for 1996 and newer.
Basically if your check engine light is off you pass. This does not mean you can clear your codes and go for the test.
You light has to be off and all emission systems passed a drive cycle.

On 1995 - 1988 its a 2 speed idle tailpipe emission test.
