work done prior = Just did a fresh oil change.
GM tech = MW
question =   Dear MW,

I just changed the oil on my Lumina.  I used 10w-40, as I always have.
I found a filter in the trunk of my car, presumed it hadn't been used
( no sign of oil on/in it).  After the change, the car has a rough
start, and makes a light knocking noise.  This noise can be heard for the
first maybe 50-60 seconds, after it kicks out.  Is it possible that
something wasn't put on tight enough?  I checked and tightened everything.
Could a bad filter be the result.  I'm hoping its not a bent push-rod
( don't think it is, because it happened after the oil change).  Any
ideas?






MW:
It is possible that you have the wrong oil filter or that there was something in
the oil filter that was sitting in your trunk. If there was some dirt, or even a  
bug in the oil filter, there is no telling where it may have ended up in the  
oiling system.
Need to have further diag to see where the noise is coming from, then find  
out why. May take some engine disassembly to trace it down. The check  
engine light is probably misfire codes

question = I keep getting a P0440 code. Is there any typical problems with the 97 Lumina
related to this code?
