P2076 is Trouble code for the intake manifold tuning valve. You need to check power supply and signal to connectors. Check also the wirings. You can also monitor from the scan tool regarding the value of the position sensor of intake manifold tuning valve and the value commanded by the ecm. Sometimes this valve get stuck and will not respond to ecm controls. ?
Try solenoid passenger side of engine. Available at auto parts stores for under $80. Test it first. 2 hoses, 2 10 mm bolts take a pic first as diaphragm valve and arm will also come off. Careful attention and mechanic sense can fix it under 1/2 to 1 hour first time including figuring it out and fumbling around.
Have to pull the plastic engine cover,on the pass. side of the engine at the end of the plastic intake
manifold there is a cover with a plastic "nut" on the top,1/4 turn and the valve is underneath,be careful to get the o-rings in right ,(2 I think) some have a small spring on top to keep the valve seated

Nm).
- Rocker arm cover using a new gasket. Torque the rocker cover bolts
to 89 inch lbs. (10 Nm). - Heater bypass pipe. Torque the screw at the water pump to 106 inch
lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25
Nm) and the nut to 18 ft. lbs. (25 Nm).

Hi,
You can sometimes (if you have 2 elbows on each arm) reach around the back of the intake manifold and replace the coil pack using a 1/4 inch rachet with a 7mm socket.
Most of the time you need to remove the plastic cowl assembly located under the windshield wipers. To do this remove both wiper arms by lifting the plastic covers at the bottom of each wiper arm. Remove the 15mm nuts that hold the wiper arms down and wiggle the arms while pulling upwards until they come off (take note of which is left and right, they are different sizes). Next remove the plastic phillips screws/ plastic rivets that hold the cowl down on the bottom towards the engine(the screw comes up half way and when you pull up the base/ rivet comes up with it).
Next pull up on the cowl where it meets the windshield left or right side and you will hear the retainers snap and release. Continue pulling until the cowl is loose. Next disconnect the hoses that go to the washer nozzles. Put the cowl aside.
Next remove the micron filter located on the passengers side of the cowl (if it has one it is a good time to replace it). Remove from left to right 8or 9 8mm bolts that hold the lower cowl down. On the drivers side disconnect the 8 pin connector for the wiper motor. Now disconnect the washer fluid hose that goes thru the cowl on the passengers side. Lift up on the cowl and you should be able to wiggle it out and set it aside. You can now see the coil pack behind the intake manifold. Take note of spark plug wire location on the coil pack because they have to go back on in the same order.. Reassemble in reverse order. Note that while the cowl is off it is a great time to replace the spark plugs on the back of the engine.
Good luck to you and congratulations for doing it yourself
