i have been fighting the dreaded drive cycle to get my emissions done in tn. i have failed 3 times due to the computer not being able to read the emission moniters. i have driven over 1000 miles in traffic conditions highwayconditions and at the dragstrip. outside temps from 93* to 65*. i still cant get the catalyst,o2 sensor and heated o2 sensor to read.
i have searched drive cycle on the web and done the driving req.
any ideas?
