It's only in startup,most using their after parking after driving. It's either the 02 sensor,or cat.with 111,000 miles on them...I'm hoping it's just the sensors.but....should I do the downstream?or both?
I think you're kidding yourself...it's the gaskets...but if you only do the O2 sensors, just do the downstream first because it'll eventually go bad and you'll be back where you started and you will waste the least amount of money that way. I guess if that doesn't do it, do the upstream too; still cheaper than the CAT and having a mechanic do the LIM gaskets. Then again, you might still get the code and the CAT may be toast...
If you shadetree, the LIM gaskets aren't bad if you take your time, have the tools and some patience - less than $100; youtube is your friend in this case. Don't know what it would cost for a mechanic to do it. I'm guessing 500-1000.
