Hey everyone I got a problem with my gt. The car runs perfect for 30minutes than i start to get problems,the car stubber and wont pass 4krpms and it's acting like it's got missfire when it does that.I checked the spark plugs and injectors for ohms they are all good.The car sometimes dies when it starts to stubbering when I come to the light,the car shakes.I also have a buddy who got a obd2 checker we checked it for codes and iat high input pooped out.p0133 code think. I was also wondering could it be the tps sensor,because it only does that when i drive it for more than 30minutes.Please help me with my problem.
thanks jacob

 

It sounds like you need a new IAT sensor, as you already stated. The reason it runs good for thirty minutes is, your engine ( when started cold ) doesn't look at the Intake Air Temperature ( IAT ) for the fuel delivery til it is warmed up ( if I remember right ). If the code says its the IAT, then change the sensor.

 

That code is not for the IAT sensor. That is the "O2 sensor CKT slow response Bank 1, Sensor 1." Either you listed the wrong code, or you need a new O2 sensor.
