Hey guys, this is my first post so sorry if this seems like a stupid problem. I searched but didn't find the exact problem im having on my motor. I have a 7mgte, basically stock aside from a manual boost controller at 10 pounds, 2.5 inch catless exhaust, electric fans, and a felpro head gasket. Everything has been running good since I bought the car aside from the fact that when I try to start the car after its been driven that it doesn't want to idle. When I start it and its cold its fine though. Its progressivley getting worse over the past few days. Today it was so bad that when I started it I had to keep the peddle to the floor and it'll sputter at 200 then shoot up and clear out. I can't figure out what it is and im running no codes. Any help is greatly appreciated.

As a first, did you check your TPS and/or ICSV ? it's aloways a good thing to start checking that first.

However, it could be something with the car instantly going into closed loop when the car is warm so I would guess that there might be something wrong with your O2 sensor. How's your gas mileage ?

gas mileage isnt amazing and i can smell alot of gas when i get on the car. I also forgot to mention that the car breaks up when i get to high rpms if i go to WOT weather im just free reving at a stop or if im actually driving at WOT
