So my 97 Max failed smog 2 times in 2 days because the smog place's device disconnects from the OBD port in the middle of the test. Handheld devices work just fine, at least the 3 I tried..
Aside from cleaning the battery terminals, what else should I try?
Anybody else run into something like this?
