The engine P2817 code seems a kind of powertrain problem and this is general problem what can be fixed fast easily. Even you do not need to add or change any part of the car engine. Concerning the engine P2817 code, it would perhaps be valuable to sensibly inspect the cable bind near the intake manifold bracket. This is done most simply from underneath the car in the part near the oil filter. Do not try to solve the car engine by the general meaning of the code if the right meaning of the code is found. Fix the car engine by a trusted technician.
