Hi all, yes, car is revving freely as it is. No real faults with the engine as it is. Just a slightly poor response from low down. Hopefully fitting the replacement air intake pipe will sort out that. Probably too much air getting in from the split pipe and running too lean.
I also have a slight exhaust leak which, if I didn't have access to a smoke tester, would of never been found. On the actual manifold where the individual ports join together into the collector, it seems a weld has gone on the inside part. This is probably adding a touch of air to the exhaust which is throwing the Lambda readings out and possibly a cause of the bogging low down.
So thats another thing added to a list that doesn't seem to be changing in length! :s
