Title: Over revving, throttle body and MPG..
Post by: JamesV6CDX on 05 March 2007, 20:02:59
On the 2.0, My engine, is slightly over-revving. At idle, when warmed up, it sits at 1100rpm (when in P or N).. and about 600rpm when in D.

When I got the car at first, I seem to recall it being lower than this.

But I've just recalled.. that it wasn't revving quite this much, before I serviced it. It's occured to me, that I did not use new gaskets on the throttle body and the ICV.. (couldn't get any at the time).. so I just used some sealent on the old gaskets.

I'm wondering if I've got an air intake leak around the TB area, causing poor MPG?

Very possible, or anyother air leak unrelated that is getting worse...

I did break off the vaccum hose that goes from the main servo/manifold thick vaccum pipe.. to the sec air injection.. but I just taped up the hole.. on the basis that it doesn't do a lot..

I think it's probably more likely the TB gaskets causing the over-rev

Might pop down in a min and read fault codes, I'm at work, but it's quiet so who cares...
