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

If there are no coolant leaks then check your engine oil to be sure it is not over full or foamy because if there is coolant getting into the oil it will cause irreversible damage to the engine. If the engine has ever over heated the head gasket/s could also be leaking and will need replaced.
