Vehicle is running rough at idle, idles too low. diagnostic code shows code # P2071
This has a double intake manifold with control actuators at the base of the manifold most are vacuum controlled the computer monitors these actuators positions. #1 locate passenger actuator and lever position with engine off put a vacuum hose on it and suck on hose and watch arm lever it should move then place tongue against hose it should hold that position if it does not actuator is bad if it does the the control solenoid is at fault or no engine vacuum to solenoid.

I had this problem also, I had all the coils checked and 2 of them were bad. The Mechanic that fixed it said I should replace all the spark plug boots and the gaskets because as they wear, they leak oil into where the spark plugs are and do two things, first the oil shorts out the coils, and secondly the oil deteriorates the boots until they no longer insulate, and that is why you get misfire and shaking. I had this done about 8 months ago and my 02 LSE has been running like a charm ever since.

Every car different, call an auto rescue or towing company, the trucks are usually equiped with slim jims, that can be used to gain access to your vehicle.
Hope this helps.

If there is an Auto Zone around your area, have the truck scanned for the DTC codes which is causing your idle problem. There are to many things that can cause your trucks idle to be rough. Once you have it scanned, we can address the issue and have your truck running 100% again. Auto Zone scan free of charge and can give you the step by step instructions to repairing and replacing the parts needed. Good luck and keep me posted, be glad to help.

I will make an assumption here, we know what the root word means. This code was extracted from the computer by? What this is telling you one of 2 things: The Bank 2 oxygen sensor down stream of the catalytic converter (there are 2 converters, one for each bank of cylinders on the 4.6ltr engine) is bad and/or that the Bank 2 catalytic converter is no longer doing the job it was designed to do. Simply, Catalysts wear out. They are good for approx 100,000 miles (as required by Federal Law). Again, I assume that the reason the intake manifold was replaced was because it had a crack in one, or more, of the runners? (part that feeds the head of a manifold). It may have taken a while to find this as being the cause of why the car running incorrectly, maybe rough. This means, that during the time the car was being driven with the problem, the amount of unburned, or not within spec exhaust gases, coming off the side of the engine affected by the intake issue was higher than normal. This out of balance level of exhaust gases were being dumped into the converter on that side of the engine, thus causing the converter to have to run hotter, work harder, or even at the time the gas was being processed through, causing deposits to be formed in the converter, thus shortening it's life span. The Bank 1 side of the engine, apparently, did not have the issue and it's catalytic converter's life was not affected. I hope this makes sense to you.
