Must pass emmissions
Ok, im in desperate need here. I did SLP LT headers, High flow cats and Loudmout exhaust about a year ago and never had to pass emmisions yet because i had it tested when i got it. now its time to renew my tags and it requires emmision testing. my SES light is on but i know how to reset it and i even have thunderracing O2 sims.
BOTTOM Line: Does anyone have tricks/tips to get my car to pass emmisions. i live in Colorado thanks in advance

i had the codes run once and it was the o2's were the problem but i guess the sims didnt get it to shut off. i guess im looking for a cheap way to pass the test but i might not be so lucky.

Youreally need to get a scanner not a code reader and
view the 02 data stream. it's the only way to find out what is really going on. You said that you have o2 sims what about the front sensors these must be left in place so the conmputor can compare the front sensors with the rear sensors, there has to be a difference between the two otherwise you set a code.
