Texas Emissions Test?

[Thin Man]

I am relocating to Dallas TX area.... and my Gen 1 "might" not have cats....... I'm not saying for sure... but might not.

I heard they have emissions testing in Texas.... is this accurate.. and how strict are the tests? Would I have to make sure I have cats on for the test.. or would there be any way around this.... if I didn't have cats... just askin'?

Parts of Texas has testing. We are located just outside of Austin in Hays County were they do NOT test. If you don't have cats, put in some rear 02 sims. That will fix it.

It depends on what county your car is registered in (i.e. where you live)

Here are the counties that do emissions testing and it will detect a cat-less motor (lots of hydrocarbons):

Enhanced vehicle emissions testing was implemented in affected areas in Texas to improve air quality. Testing began in Dallas, Tarrant, Harris, Collin, Denton counties on May 1, 2002 and began May 1, 2003 in Galveston, Brazoria, Fort Bend, Montgomery, Ellis, Johnson, Kaufman, Parker, and Rockwall counties. Vehicle emissions testing continues in El Paso county. Testing began September 1, 2005 in Travis and Williamson counties.

Gen 1 Vipers are not OBDII compliant. Therefore, they will be sniff-tested. '96 and later cars will be checked for emissions fault codes set in the JTEC controller. If the rear O2s aren't reading the correctly anticipated O2 levels downstream of the cats, they trigger a fault and you don't pass.

Good info... one more question though... is the 1996 RT/10 OBDII compliant? Seems I recall reading somewhere that it is.

It has not thrown any error codes ......

Yes, the 96 RT shares the JTEC controller with the later cars and is OBDII compliant.
