1999 Accord Cat

You should get the exact codes that were pulled. maybe take it to Autozone, they pull them for free. Then you can check. If a cat goes bad, it's usually that the innards break up, which can cause rattling and driveablility issues. It may simply be the O2 sensor. At any rate, aftermarket cats are significantly cheaper than OEM - which it sounds like your guy was quoting.

I had this happen to my 99 accord in 2003 or 2004. My cat was replaced under some emission recall or Honda emission TSB. I don't remember what my check engine code was. You may want to hunt these links for your problem. $1000 is what the dealer told me it would cost if I had to pay.

Thanks guys.

So the saga on this continues somewhat, I had the CAT replaced and although I asked for an aftermarket there was none available. Another factor is that about a month prior I had the timing belt changed and also all the other belts and water pump, plus new front brakes and rotors.. $1300.

So, we had the work done and they replaced the CAT and associated hardware and the total bill was $1386!!

So, put on a few hundred miles and it was fine, and then .....yep... check engine light. Only now my daughter has moved out of the area and she is in New Jersey. So she gets an appointment at a dealer down in new Jersey, D&C Honda and she drivers over there.. to get them to read the code.. just before she drives in, the Check Engine light goes out.

The Service Manager tells me there is no sense in reading the code as it is "probably a gas cap code" but also that if the light is off, the code isn't stored. he says on a 99 it isn't stored.

Any idea on that from anyone?

Anyone buy the "Gas cap theory"... feels like a blow off to me.

Thanks,

Steve

PS She is in Leonia NJ, anyone have a suggestion for a good service place down there?

Not usually.

I believe they ARE stored;if the CEL(check engine light) comes on,that means a fault has been detected,and the ECU stores it until cleared by a scan tool.That's deliberate,so that intermittents can be troubleshot.

there are OBD-2 codes that could indicate a gas cap wasn't screwed down tight enough. It's part of the evaporative emissions control subsystem.

The car could have some bad hoses,maybe a crack that intermitently triggers the CEL.

Thanks Jim, we're keeping an eye on it now.
