Hi Scotty . I have a 2002 Nissan Altima
I had check engine light for camshaft position sensors bay one and two. I changed both sensors . Bay one and check engine codes are still active . Car is sluggish approaching 35-50 MPH
And cold starts and temps have low idle and even stall with out pressing gas a little
I’ve cleaned connectors to sensors , tuneup, and MAF spray through the throttle body with engine running .
