:1zhelp:i just got my supra out of the shop after swapping a new motor. i floored it kind of and as soon as it went to the high rpms it jerked and wouldn't speed up anymore. i tested the codes and it shows 34 which should be the turbo pressure sensor and 52 which is the knock sensors. but the same thing happenned in my old motor and the knock sensors are not the same as the old motor. any ideas would be very helpful to me. thanks.:1zhelp:

Test it out. It's not hard and should be considered routine maintance.
And Knock Sensor rewire time. There's a great write up on supras.com

As for code 34- That's likely caused by a boost leak. However, if you prove that there is no boost leak, and you're absolutely certain, do a bench test of the AFM. Here's how: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=FI&P=96
