need Help, just installed budget y pipe and UDP, car is sputtering

Not sure if there is any correlation, but my car acts like it is choking when trying to accelerate, sputters and hesistates. My obd2 scan tool reads, 0401 intake temp sensor. This sensor plugs into the stock airbox, but i have had a short ram intake for over a year and have not had this problem. Also I am getting, 0325 knock sensor, i do not believe that this effects acceleration. Could it be the Y pipe from budget??

Sounds like your MAF... check if that is plugged in properly.

The y-pipe alone will not cause these problems (at least I don't think so). Perhaps the O2 sensors were damaged during the installation.

The UDP has a pickup for the crank position sensor (REF). There have been issues with hard starts and engine performance after a UDP install. Go over your work and make sure the timing ring is correctly installed on the UDP. It could be defective.
