I took it to the local Nissan dealership on 1/22 due to check engine light and would not pass emissions. The dealership replaced the exhaust gasket for a cost of $410.00. Cleared the check engine light and it has failed retest twice. The test results at 2 different stations were failed due to (readiness) I have driven at around 100 miles on first test and another 100 miles on 2nd test. I only have 3 days left before the temp registration expires. What else can i do?
