CEL P0507
My RPM's are a little higher (1200) and I'm assuming it's the intake air control sensor that needs a little cleaning or replaced. What else can it be?

I found this, its for a jag but still might help some:
Idle Speed Control – P0507
Model:
Jaguar XJ 1995
Complaint:
The fault code P0507 is likely to be set due to a high fault in the ISC RPM in Bank A.
Remedy:
Ensure the code P1111 has been logged after the service drive cycle has been completed. If this is not the case then go to step 10 of the test below.
Check the harness and connectors to ensure they are in good condition and are reliable. If they are faulty then either repair or replace and go to step 10 of the test below.
Go to step 1 of the test below; if no faults are found.
Test:
[ul][*]Ensure there are no blockages in the intake air system. If not then go to step 2. If it is blocked then repair or replace valve and/or ducting and go to step 10. [*]Ensure the throttle valve is working sufficiently and not sticking. If it is not sticking then go to step 3. If it is sticking then repair or replace and go to step 10. [*]Ensure the accelerator mechanism is working sufficiently. If so then go to step 4. If it is faulty then repair or replace the mechanism and go to step 10. [*]Ensure the ISC valve is operating correctly. If so then disconnect the bank A ISC valve and go to step 5. If it is faulty then repair or replace the valve and go to step 10. [*]Check harness insulation PI 029/001 will complete a circuit to ground. If this gives a positive result then go to step 6. If the circuit shorts then find and repair the wiring fault, re-connect the harness, and go to step 10. [*]Check harness insulation PI 029/002 will complete a circuit to ground. If this gives a positive result go to step 7. If the circuit shorts then find and repair the wiring fault, re-connect the harness, and go to step 10. [*]Check harness insulation PI 029/003 will complete a circuit to ground. If this gives a positive result then go to step 8. If the circuit shorts then find and repair the wiring fault, re-connect the harness, and go to step 10. [*]Ensure the MAP sensor filter is working correctly. If so then go to step 9. If it is blocked then clear the blockage or replace the filter, re-connect the harness and go to step 10. [*]Ensure the MAP sensor hose is working sufficiently. If so then go to step 10. If it is faulty then repair or replace the sensor hose, re-connect the harness and go to step 10. [*]In order to check if the fault code has been cleared perform the service drive cycle. If this gives a positive result then stop. If the fault is still present then go to step 11. [*]Repeat the diagnostic procedure. If this now omits a positive result then stop. [/ul]
