had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

SOURCE: KNOCK SENSOR
When a knock is detected, it sends this information to the computor, in which retards the ignition timing. If the sensor is bad, it will do this more often than not.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

Clean the sensor wire in the mass air flow sensor. Remove the tamper proof screws to remove the sensor holder and clean off the wire with carb spray or brake cleaner. Do not touch the wire with hands or rags.
