You can check for an intake leak, spray some carb cleaner and listen for a change in idle. Monitor your o2 volts.

i did spray carb cleaner and i guess it does have a leak....... my problem is now HOW DO YOU TAKE THE INTAKE APART with out taking the whole engine apart...... please someone help..

Just pull the intake back from the head. The intake will not come out while the engine is still inside the vehicle.
