idles rough

1988 pontiac bonneville with fuel injection idles rough when warm.
Any ideas what can cause this.

Many things can cause a rough idle. Off the cuff, start simple! The engine needs fuel, air, and spark, so check for: fuel pressure, clogged air filter, and condition of the spark plugs and wires.

Repost here, but also be sure to search the archives - there are a lot of discussions threads that can help.

Also fairly simple is this wonderful page of instructions from Padgett:

Can't beat the price, either.

Thanks
