for those who live somewhere with an etest it seems that my car didnt pass etest i just bought it, its a 1996 acura 2.5tl the exhaust looks brand new everything except the cat and the guy who did the etest told me that its more then likely my cat here are my results any help would be apprecited!

asm 2525 LIMIT READING
HC ppm 58 105
CO% PASSED PASSED
NO ppm 435 3234


if i do need a cat will a cat from a 3.2tl work the same as one from a 2.5tl? will they be compatible?

 

no they're different just buy a replacement aftermarket one and make sure you don't have other issues. Like mine I need to clean out all egr ports from egr valve to bottom of intake manifold but to much trouble so I might just cheat it not sure?

 

so an aftermarket one will pass? and how would i know if the EGR ports need cleaning?

 

It should if you have less than 150k on the car, the Acura Stealer can do all emissions work for free just show proof of the etesting results and they should take care of it but you can install an aftermarket one. As far as the egr ports if you have a check engine light on, have someone check the trouble codes and look for P0401 something like that it means insufficient egr flow which is just carbon build up on the intake manifold and so on. On your test it should have labeled all the components that passed and the ones that didn't such egr,thermostatic air cleaner,catalytic converter, and so on... check which ones did and didn't then you can narrow it down. Check it out and get back with the results okay.

 

If you are below 150K miles, go to the dealership with the emissions report. All 1996 and 1997 Honda and Acura vehicles are covered by Honda upto 150K miles..

 

^ OR 14yrs... My check engine light came back on last week for the insufficient EGR flow. I called Honda Corporate and they told me that my warranty have expired.
