Nice Thread you guys got here. i havent had time to read the whole thing but i did happen to find a few people that have been expieriencing similer idle issues at start up...but have found little in terms of a solution?
let me start by mentioning that i completed my swap 2 years ago this spring. i kept mostly everything stock with the excpiton of a chip and the standard breathing mods. and i must say it was by far the most simple way to put a 16V into a late mk2! Everything went Smoothe and with the excption of having my feed/return fuel lines swithched somehow ...
the car started/ran/revved and pulled hard off the first crank. the only issue that had me purplexed was that of a serious bogging when i gave it full throttle from idle. i thought it was an ignition issue but with everything set up to the book the hesitation was quite evedant.
after alot of playing around, trying slightly different settings of timing Air/fuel mixture and idle i finally got it to idle just over 900 rpm and rev up smoothely right from idle...to 7000(as far as ive taken it)....
However it comes not with out SACRAFICE.
since clearing this hesitation up it has the worst time finding an idle for about the first 30 secconds after start up. it revs up and dies off back and forth seemingly hunting for a specific range. it always settles down and is problem free with great idle and strong accelleration.
i havent tried setting back to exact spec because its only been taken out slightly.
As for that problem ill keep plugging away at a few ideas that i have to solve this and ill keep updatad.
But one thing i have been curious about is my crankcase breather hose. Should that be meterd air or not ive seen people run it both ways. into the intake pipe, into the bottom fo the air box and not at all with just a little cone filter on it. whats standard? id like to hear any input on this.
other than that i couldent have a more reliable fun to drive mk2 for the money i have into it!
thanks for reading
