Chrysler Repair: Oil light flickers and engine dips at idle, engine oil pressure, oil pressure switch


Question
QUESTION: Hi Kevin - I appreciate the help.  I have a 2000 Chrysler Condcorde.  We bought it used about 4 years ago.  It had 19k miles on it.  I drive a long way to work and so now, four years later it has 132,500 miles on it.

Recently, on occasion, when stopped (at a light) the engine RPM drops below 500 rpm and the oil light flickers.

I change the oil every 4000-6000 miles but don't want to be stuck if the engine is building up sludge etc.

Anything I can do to check this out or fix it?

Thanks so much,
John

P.S. We've been trying to decide on trading this in, or keeping it a while longer (but want to be sure it'll keep running and be safe).  I've had no major (or minor) repairs that I can recall with this car so far and almost all the mileage I've put on it is highway miles.  Any preventative maintenance you definately recommend to keep it going another 100k miles?  Thanks!

ANSWER: what engine size?

QUESTION: Sorry - 2.7L.  Also, this weekend I took it to Autozone and got a free diagnostic check (well, whatever you call it when they plug in the computer code checking tool) and it came up clear - no codes.

QUESTION: Thanks Kevin.  This appears to be a TSB for this car then?  Is this something I could do (sounds simple enough) or should I take this TSB to a dealer and ask them to do it?

Should I change the sensor itself while adding this part?  (What does this do, just bleed off excess oil?)

And what does the last line "Reimbursable within the provisions of the warranty" mean?  If I had an extended warranty would it cover all TSB work?

Answer
U can do it yourself  takes 5 min   replace the oil pressure switch  if its leaking  yes.  the last line is if it is done under warranty  and  no I can no say if U have one or not  its not a recall so if U are out of 3 36  or have some sorta after market one  it wont be covered.
