Engine Mechanical problem
2004 Cadillac SRX V8 Two Wheel Drive Automatic 99000 miles
Yesterday I had the SES lite come on with codes P0430 and P0341.
Once the car warms up it runs and sounds fine. But when first starting cold for the first second or two it sounds like it will tear itself apart. Lots of mechanical noise and clanking. This is a new simptom.
One of the codes is for the catalyst. I am looking in to replacing that. But I am worried that its only a "downstream" problem. The other code is for "cam sensor performance". This one worries me more. If this sensor fails could that cause valve/piston interferance and damage?
I've reset the codes and so far they have not come back. But the cold start noise bothers me much.
have the same problem?
