I recently went to have my car smogged here in San Jose, CA. At the first shop i went to the guy said that his machine wasn’t pick up the rpms so he couldn’t do the smog check. He said it might be the machine and to come back later. Later i came back, same result, so he said try another shop. I go to the other shop…strike 3.
I asked the guy at the second shop why he couldn’t just take the rpm reading like they do on previous model years from the distributor, and he said, “blah blah blah visual inspection, blah some kind of excuse” i wasn’t really listening.
The tach on the dash is reading the rpms fine. I have no CEL and the car runs smoothly, gets good mileage, and no weird noises.
So is there an easy-intermediate DIY fix for this?
