Hi, We bought this car about a month ago. It passed safty no problem but the emissions test it keeps failing, We changed the fuel pump, spark plugs, distributor cap, catalytic converter, O2 sensors ( the right front one), There was a few other things but i can't remember what they are called. one i think was a vacuum and another was a hose of some sort..sorry.
Anyways We went and got the computer reading done and found out the problem was the other O2 sensor ( front left ). so we changed that one. Still failed but the readings were down alot. The computer reading is coming back as nothing is wrong.
This is what it;s reading now.

HC ppm Limit: 66 Reading at 128
NO ppm Limit: 505 reading at 557

What else could it be..Please help i have 3 days to get it E-tested before i have to safty it again.
Oh and its a V6 engine.
Thanks in advance :)
