Matty-H

Righty I've done away with the K-STAR and I've set the idle and ignition timing again, runs better if anything, power is consistent through the rev range and the exhaust note is a lot more deeper opposed to before with the K-star and the ignition timing being fully advanced. Does not smell as rich any more and the burn smells pretty clean. Also changed the plugs as the oldies were not up to much either. Also the oil temperature used to read over 110 - 118 at some points during driving and now stays around 96/98 degrees. I'm looking into vacuum pipes again and noticed there is one that comes off the bottom of the 5th injector housing and goes to the crank case breather pipe, then off that and along to the air box. Surely that's not going to help? Picking up air from the inlet before the metering head I'd have thought it may make it run lean? or is it just another daft place for it to pull in crank case gasses and ''recycle'' them? Also there is a vacuum pipe blocked on the bottom of the inlet manifold just above the alternator. I really could use some diagrams so I can be sure to get to the bottom of everything.

I'm hoping to get some time on her this weekend David. Trouble is now It's burning oil like a tank too.. I will still have a go at getting her to run better still. Also the idle is being odd too, I've tried resetting it a few times and it seems to be fine for a while and then starts to raise slowly over a day or so to around 1100rpm regardless of the engine being at normal operating temp or cold.. correct procedure followed when I have done it. WUR is ringing a bell for me, Am I right to suspect this?

I am fairly familiar with the k jet system but never really spent a lot of time working on them. I am a mechanic by trade, had a lot of mk2's and completed many engine conversions, rebuilt engines and all the rest. It riddles my head with worms when seeing all the pipes/vacuum lines on K-Jets lol! I'm more used to the Digifant side of life from previous experience with ABF's and later 8v's. The things I've already checked are the vacuum lines and all fairly obvious things like the inlet pipes/metering head/plugs etc. I've changed the whole sender unit/lift pump a few days ago as the gauge was not reading correct and the lift pump was a bit worse for wear. All that side is working fine and the main pump sounds sweet with no nasty whines or buzzing. I'm led to believe from what you have said and other posts on here and elsewhere it could be down to a fuelling issue.. I can feel it being a long journey with the old lump and I am pondering a better upgrade without going over the top

Just wanting to pick your brains. I've recently purchased a 1.8 16v and all is well apart from it feeling very under powered and sluggish low down. Its also absolutely rubbish on fuel. All the engine timing is bang on as I replaced the cam belt at the weekend thinking it may have been a tooth out etc. Turns out it was not and was and is still all correct. Its so flat under load especially at low rpm and only seems to pull after 6k. Anyway I was having the odd look around and found the distributor was fully advanced and it felt even worse when corrected to 6deg standard timing. Shortly after I found ''K-STAR'' hiding under the scuttle tray, all intact and plugged in.. I know the purpose of these piggyback ecu's were mainly to stop pinking when running on less than 98 octane fuels, and that they work in 500rpm increments adjusting the ignition timing to suit/overriding the standard ecu. And that they work with the ignition timing being fully advanced. I then tried it without the K-STAR, Set the timing to standard and it was even worse than before! Any ideas? My friends 1986 1.8 8v Mk2 golf puts me to shame and pulls/feels a lot better than my KR and leaves me standing..

There should be a pipe that comes off it straight to the airbox.

Hi all I'm Matt. I'm not new to the vw scene having owned Loads of golf mk2's, polo's and the odd other vw's. I've wanted a Corrado for years (Ideally a VR6) But I can't afford a good one. So I have settled with a 1990 1.8 16v In black, The car is well known and is a good example and I'm just starting to sort bits slowly. Anywho Here's a few pics.

I don't know him personally but maybe some of you do? cheers
