Rough idle on my 929

So one day I went to take my skill test and practicing in an empty lot. Passed my test heading home excited. So I rip a little on the highway get to my location. And going to leave start her up and idle sounds weak. Then gradually gain to 900 without giving I gas. Before this at warm start up she would idle 1100 1200 now she won't go above 1000. So I ride her get home same thing. Seem weak on the power as well. So when it parked running I brought the rpms up to 2000 held it steady but it was jumping between 1900 and 2100 r's and running super rich. All this just happened out of the blue. Cause I've ripped her way harder than this. Hoping nothing major.

Any help would be amazing. Thanks in advance.

Mike

Check fuel pressure regulator vacuum hose is not sucking fuel.

Ok I'm going to check that first thing in the morning. Cause that's what I was thinking too. Because if I give it throttle it will sit at normal rpms for 1 to 3 seconds and then drop again.
