Why did he not use your intake? That could very well be the source of problem, at least on the P1705 code.
Here is information on that, located at this website.
P1705 excessively high or low voltage input from TPS sensor
When testing a tps sensor code like this P1705 code, check the signal wire voltage for any signs of glitch. This can be done manually without running the engine. With key on engine off, monitor the signal wire voltage from idle (close throttle) and up to high idle (WOT or wide open throttle position) by moving the throttle linkage. The transistion from idle to high idle should be reflected in the voltage readings like a gradually increasing pattern. If there is a sudden change or a glitch, replace the TPS sensor. Please note also that a regular tps sensor usually has 3 wires: a voltage reference wire, a signal wire and a ground wire. Except the signal wires, the other 2 wires should have steady voltage readings regardless of the throttle linkage position.
For advance testing, garages can usually monitor the voltage of the TPS signal wire while the engine is running. Using a special scanner, the voltage can be watched while cruising in order to see if the value of the signal wire voltage will change. This is particularly important if the code P1705 only appears intermittently. For precaution, check the integrity of the signal wires from the TPS sensor plug-in up to 12 inches away. To do this, splice the wiring harness and check if there is any short (bump) in the signal wire which could be rubbing metal before this code came on.
With regard to the AT Oil Temp light and non-shifting, I wonder if there is a connector not properly seated on the transmission - it sounds to me like the engine control module and transmission control module are not talking! They have to talk if you want the tranny to shift out of 1st. By default, it will work in P, R, N, and 1 without input from the engine control module, but that unit tells it when/if to up or down shift through the other forward gears.

I am having this same problem on a brand new 2011 subaru forester. The check engine came on the night I drove it off the lot and has come on 6 times in the 3 weeks that I've had it. It is engine misfire trouble codes P0302 and P0304. They don't know how to fix it. I sent in my lemon law letter and I am trying to get them to replace the car with another one.

I am having the same issues with the check engine lights due to misfires as well as numerous transmission issues with no codes showing problems. I am now requesting a repurchase.

I have a 2011 Forester auto and traveling up hill it surges and shakes before downshifting. It also feels like it slips into neutral before hitting the lower gear really hard at low speed city driving. The computer is not showing any problems with lights or codes about the transmission and the dealer has had it 6 times attempting to resolve this issue with no luck. I say LEMON!

My less than 1 year Forester has been in 4 times for misfires. Each time, the dealership tells me it is for a different reason.
The Lemon law in California states that if it is brought in for four times for the SAME thing.
I have secured an attorney to deal with Subaru.
