Failed Texas emission test
Hi Fellas, I haven't posted in a while because my Jeep has been running pretty well. Anyhow, I took it in for the annual Texas cash grab and failed the emission test and retest. $39.50 out the exhaust. My Jeep failed on CO and NOX. 3.37 CO & 1471 NOX at high speed (25 mph).
I have all of the original pulse air crap working properly, no exhaust leaks, new air filter, and replaced the egr valve about 10 months ago.
I could use some advice. I'm hoping it's something simple, but my gut tells me it's never that easy. Anything that could be offered would be greatly appreciated.
