Catalytic Converter queston......
About to smog my 92 for the first time in CA this friday...... according to my Carfax the car passed CA smog in 2002 at 135,620 miles and 2004 at 135,878 miles. I now have 140,000 miles roughly........ that being said...... since it hasnt been driven much since last passing smog, but was 4 1/2 years ago.... is there a reason I should think it wouldnt pass? I installed new plugs and other maintenance and it runs great and idles smooth..... so there wouldnt be a reason for a cat to go bad within 4500 miles right, even if its been over 4 years? Im just wondering if time has a role in fouling or diminishing the effectiveness of the cats.

Re: Catalytic Converter queston......
Hi,
Mine passed smog two weeks ago at 163,000 miles. I get an occasional CEL, but they refer to a weak knock sensor and something in the EGR system. I warmed the car up fully by taking it on a 20 mile freeway run, brought it to the smog station, and half an hour later, my certificate was on its way to Sacramento. I don't know what the problem is with the EGR, I suspect the valve sticks every once in a while. I'm sure the knock sensor is cracked, because the CEL comes on if I make a left turn shortly after starting the car from really cold (several days off.) It usually goes out after a minute or so, only once or twice staying on for about 50 miles. The dealer wants $800+ to fix both problems, but I think he is double dipping, flat rating me on both, both of which require removing the intake manifold, a two hour job at flat rate. Anyway, I run on. GEt it smogged, and enjoy. Paul

And congrats! You had me scared in another thread saying you'd get rid of it if it failed. Glad it didn't come to that.

Curiously, when my whole Reno debacle happened it failed NV smog miserably at idle and revs. Im thinking that after it finally started and smoked like crazy for a minute burning out all the excess fuel it fouled the cats before I smogged it there...... but cleared out when I drove it back to Socal.... thats the only way it could go from terrible to clean im assuming |
