1. Im tryin 2 work on my motor for the 1st time Im pretty good at figuring out things, I dont have money 2 bring to the shop rite now but yea ne whaz, the egr is throwing codes, and its doing that idle thing going to like 1800rpm and dropping to 1000 then going up and doing it again (at idle that is) so , wen this started happening my mechanic said its most likely the lines not the valve itself so have any of u had this problem and fixed it urself? and the second thing is any1 have a website for a h22 engine guide book, you know showing all the componets and code numbers and what not , thanks .

 

Look in the essential links at the top of the Prelude page. There should be codes in there. Best thing to do is take the egr off and clean it out.

 

It sounds to me like either a vacuum leak or your iacv is bad.
