I'm now contemplating the R&R of the intake manifold to get at this leaking hose. Is the R&R of the intake manifold a straight forward bolt on, bolt off procedure? Anything to replace besides the gasket? I have the MB 104 service manual and it looks doable. What makes me apprehensive are these steps:
1) check and adjust throttle control if necessary
2) check and adjust idle speed if necessary
3) read out DTC memory abd erase if necessary.
If I am able to replace everything as it was will any adjusting be necessary?
