Changed Catalytic Converter - Toyota Nation Forum : Toyota Car and Truck Forums

EMCMRI · 02-24-2009, 02:46 PM

I changed my Catalytic Converter on my Toyota Camary 2002 . It was the one that comes off the manifold , the header and all . And while i was changing it i took off the Ground on my Battery so the Check Engine light would go off . It was off after i started the car after completing the Converter Instillation . The car runs great but i am having a problem with the car Ideling when you stop it dies , Is this related to where i took the battery terminal off and the Computer is going to have to relearn its self or what would cause this to happen. Any and all help would be appreciated .

Thanks

For future reference your Camry is a Gen 5, not Gen 3, I changed the little "Gen" pic beside your thread for you.

everytime you reset the ecm to clear a code by disconnecting the battery cable for more than 10 mins, you must drive the car for at leats 10-15mins as you normally would drive it to allow the ecm to recalibrate itself to your driving habits and learn its correct shift points and idle speed.

I saw a $16,000 question on Who wants to be a Millionaire last night: "What precious metal is accumulated inside a catalytic converter that makes thieves steal them from cars?"

The lady did a audience poll and ~50% said Copper, so she confidently chose Copper. (I thought so too)

WRONG

It's Platinum! She walked away with a $1,000

So need to let it idle for about 15-20 mins then, Correct it die if you take your foot off the gas pedel.

Someone told me that i need to clean and wipe out all the varnish/carbon from around the throttle body and throttle plate make sure this is SPOTLESS, then reassemble and restart, the car should stall one or 2 times and then run normally, the car has to compensate for carbon restricting air flow and recompensate for idle. Problem solved

Have you heard of doing this , if so how big of a job is it to clean this out .
got any instruction on how to do it

Thanks

Disconnect your battery for about 10 minutes again to reset your ECM. Then when you start it put it in drive and let it idle for a good 10 minutes.

+ 1 i forgot to mention that you also have to let it idle for a bit too...my fault!

I think they mean not idling but driving around town for like 15 minutes.
