Hey Scotty I have an 06 altima 2.5 with about 116000 miles engine light came on and takes about 5 to 6 secs to turn on so I took it to auto zone and codes p0335 and p0725 came up so I changed the crankshaft position sensor still have the same problem and engine light still on any suggestions?

No. 1-1


on those, often a stretched timing chain does that, have that checked first, and pray it's not starting to blow the head gasket which those are known for
