I have a 97 Intrepid that has had a recurring check engine light
problem that turned into a rough idle and intermittent rough running
problem.  The oxgen sensor has been replaced as well as the intake.
The problem went away and has now resurfaced. When the engine is cool
it runs fine.  After the day warms up and when I drive home, after 20 -
30 minutes it starts to lose power, the check engine light blinks and i
have to ease off and feather the gas to get it back.  If i have to slow
or stop, it is so rough the car feels like it is running on half the
cylinders, and at times the transmission won't shift properly.

The fuel pump was replaced about 2 yrs ago.

Any ideas?
