Urgent help needed for emissions testing
Prior to the emissions test, my husband replaced the spark plugs, and had to unhook the battery. 2 days later, he took it for the test. It didn't pass, it couldn't read his computer. So we drove it around for a couple days, and retook the test, only to have the same thing happen.
The tech told me out of 12 it could read all but 2.
Is there a simple fix for this besides taking it in somewhere? We can't afford to, but he needs his car.
