Whats the problem?

If all you hear is clicking, then the starter's not getting enough power from the battery... This problem could be a weak battery, faulty wiring (I've even encountered squirrels eating the wires!), but the most likely culprit is usually a weak or bad (dirty) connection between the battery clamps & battery posts. They need to be clean (both the clamps & the posts) and also need to be tight on both ends. After servicing these, I'd recommend using an anti-corrosive product. (there are numerous methods & products) A good solid connection may also fix your other problems.

To find an intake leak, you can spray carb cleaner around each port with the engine running and listen for engine sound changes. This also works on vacuum hoses.

Any vehicle will run poorly with an intake manifold leak. One easy way to test for a leak is to (while the engine is still fairly cool) spray carb and choke cleaner/starting fluid around the base of the intake. You only need a small amount: if there is a leak in between the manifold and the heads, your RPMs will increase until the engine sucks all the carb cleaner in.

probly sumethin rong w the baro sensor--that relays air pressure--disconnect plug at computer then plug bac in see if system reboots--or get a scan done at a private shop that has factory gear--a code reader at a dealer or partstore wont cut it--u need values of components compared to normal
