+1. Thats what owning a Jeep is all about.

 

wait wait wait....what PART of the smog test did you fail? The different tests point to different components/issues. Reply back.

And those prices are ludicrous! an o2 sensor costs $50 and can be replaced by a monkey in 5 minutes. And you probably don't need a tune-up just to pass smog, unless it hasn't been done in a long while or is not running well.

 

CO% was at 1.72 and 1.66 when the limit is .46 and .56 haha

 

Since you failed CO (only?), there is no way a cracked header would cause it even if there was a crack.

ok i would do these things in order:

1. Oil change - big cause of CO failure
2. Air Filter clean?
3. change the o2 sensor (upstream - before catalytic converter)
4. clean the throttle body

Other things that can cause this are a faulty MAP sensor, Coolant Temp Sensor, or Throttle Position sensor


Also make sure the car is fully warmed up - take it for a SPIRITED drive prior to the test, and wait a week or so after changing any components before retest for the computer to adjust.

 

hmmm. the other stuff i should still get done though. i also failed HC(PPM) but they said it was only because i failed the CO area so badly

 

They are correct, a high CO will usually cause a high HC reading as well. Get tested after doing those 4 simple things and see if it passes. I'm betting it will.

 

Let's remember a crack in the the header will cause a O2 to malfunction and give incorrect readings.

I'd start by fixing the leak first before condemning the O2.

 

im so glad Ohio got rid of that bullspit

 

so water cooler is now added to the list. the cherokee broke down today while driving.

 

water pump? so it over heated? like everyone has already said those prices are ridiculous. someone with a welder could fix the header for free. you might not need all of that to pass smog anyways. where in CA are you located? theres a smog place near me in La Habra that was really cool when i got mine smogged. he was really cool and about everything and i'd go back to him any day.

 

water pump= $30 at pep boys

 

whittier. i got it smog tested in la habra. is this matt??

 

pep boys ftw

 

yeah its matt haha. i just looked at the OC xj owners thread and saw you posted up a pic of your xj. i had no idea you were on here haha.

so did you go to the guy off whittier blvd. accross the street from la habra high?

 

haha this is soo random. ya i love this forum! i went to the one on whittier blvd a little further past lh high. its down right past euclid.
