i have a 95 v6 3.4 and it keeps failing due to emissions, high hc ppm's and co levels, it also fails for high and low idle.

i have done: cat,egr valve,o2 sensor,cleaned the throttle body, throttle sensor, tune up.

is there anything else i should know or do?

 

go to a different shop 95 and older should be exempt from emissions

 

^ Not in all states.

 

I'm in NJ, the car drives good other than the pull or lag

 

ohhh... learn something new everyday

 

Up until a couple of years ago, IL was 1968 and newer had to get tested. 96 and newer was plug and play, 95 and older got the dyno/sniffer test. For some reason, my 69 wouldn't pass.
Some states still require older cars to get tested.

 

and here brand new cars dont have to be tested theres not even a visual emissions test

 

Here too, till they are over three years old.

 

this all has nothing to do what i posted about. i was looking for help in fixing it

 

no emissions at all here just a safety test every 2 years
