    My 98 DeVille D'Elegance starts fine when it's cold. Starts fine when it's warm, but in between, it's a rough starter. If it sits 1-20 minutes, or longer than an hour, it starts right up. From approx. 21 minutes to 59 minutes, it starts rough. 176k on the odometer. DIC offers nothing. Ideas? What could cause this?

    Hard to start, or starts and runs rough?

    Have you read the "sticky" thread on how to pull codes?

    I have pulled the codes. No clues there. It's hard to start during that brief period, but runs fine once it's started.

    Have you checked for a leaky FPR?

    Fuel Pressure Regulator. Do a search. It's been discussed a million times and is so easy Stevie Wonder could do it.
