99 996 hard to start searching Idle

[ynotony1966]

After a drive I park my car for several hours and it was hard to start. This came out of nowhere. I noticed the idol was searching. Now it's hard to start when it's cold. It cranks over just fine but I have to pump the gas quickly to get it to start when it's cold . Any ideas. I've searched threads but they don't seem to be specific for my issue.
