I am new to this site and think that the info here is great. I got a 96 maxima and the engine light came on. i took it to get a diagnostic check and the codes PO325 and PO734 came up. i am sure the PO325 is the knock sensor, but the other one is a problem. i talked to 2 nissan dealers and one said it was my solenoid valve and the other said it was the throttle position sensor. when driving at low speeds the rpms go to about 3500-4000 rpm before changing to second. when i really gas the car the rpm will go to redline unless i step off the problem, when i reaccelerate the gears switch okay. what is the problem and how much is this gonna cost me to fix (canadian funds)

thanks for any help
