Well it is a month later and I have to admit I was wrong. The manifold gaskets are leaking and the idle is erratic. I would still like to fix this myself . I have read in other threads that it isn't a difficult job.
I used carb cleaner to test the gaskets and the idle started to increase. So my question is how to remove the manifolds, bolt heads look different than any tool I have .
Could anybody guide me in this effort. Do I need to remove the throttle body for access to hoses ? I should be able to get the gaskets from a MB dealer. Also should I use a permatex product to enhance the seal as my car has been heavily modded by the previous owner.
Not only saving $800. but the feeling of acomplishment would boost confidence to do more wrenching on my own.
HELP!!
