Hi --
I live in Massachusetts and my 97 Nissan Altima failed the state emissions test -- the check engine light was on (had been for 1.5 years without any problems) -- I went to a state-registered auto shop. They performed the OBD -- that gave 2 codes. One for a knock sensor and the 2nd for a crankshaft position sensor. They replaced both sensors. When they did the repair, the electrical system had to be reset. I had driven the car over 200 miles and still one system needed to be initiated. At that time, a new code appeared, again indicating that the knock sensor was a problem. I drove the car another 200 miles and I have taken it back to the auto shop and the electical system is still not "Ready." By the way, the check engine light has not come back on.
- Is there anything I can do to get the car "Ready"?
- Is there something else wrong with my car?
Please help! Thanks.
