Warm starting issues

[Miss 180]

Sooo I just got my front mount on 2 days ago. She was running perfectly then yesterday I left the car running while i ran inside to grab something, well when i got back in and started out the drive way it started sputtering at 2.5ish. I threw it in neutral out of reaction. Went to go again and it did the same all the way through the gears. It was like it just didnt want to go. Checked all my piping to see if anything blew off and all vac lines are fine too. So I turned it off and then it wouldnt start again. Once it cooled down it started but real rough. Went to drive and it ran fine. Now cold start it starts fine. Warm, starts real rough, if at all. Still runs rough every once in a while in higher rpms.........any ideas?

Check the MAF. The wires or plug may have wiggled loose when you were messing with the IC piping. Rough starts and the inability to rev over 2500 is usually indicative of the car going into limp mode.

yea that was the first thing i checked. maf connections are good. no codes thrown on the ecu either. a new addition to the rough starting is a "pulsing" idle when warm. It feels like a vaccum leak but ive taken them off and made sure they are all fine. no luck. ive got a friend gona sell me a boost gage so i can see the pressure for sure. so we shalll see.
