missing my NY 914 in VA  Group: Members Posts: 1,338 Joined: 26-November 07 From: Oakton VA Member No.: 8,376 Region Association: MidAtlantic Region  |
Hello 914World, While I answer a lot of questions, I rarely post, BUT I am not well versed in D-Jet. I am having an issue that seems like it should have a simple answer, but so far, I am missing it.
So I am putting back together a 2.0L recently rebuilt for a friend and once I got it all back together, and once it started, the engine won't come down below 3K RPM. (IMG:style_emoticons/default/WTF.gif) I am assuming this is some kind of Vacuum leak, maybe? It runs strong and smooth at 3K but doesn't go down with closed throttle. SO, the engine is all new and I need to break in the cam, which, while 3k is probably ok, I'd like to get it sorted before I do that 15 min of 2k RPM. I've checked all the vacuum lines and connections and see nothing wrong. I am thinking to get a smoke machine, or similar to try to see what I may have missed. I am an L-Jet Guy with little experience with D-Jet and would LOVE some pointers or suggestions. (IMG:style_emoticons/default/pray.gif) Thank you in advance and I did do some searches and haven't yet found anything like this. CupO'Meat! (the car is a 74 2.0L and I used Jeff Bowlsby's vacuum line diagram to double check) |
