the ecu is fitted now... yep si's right, the one that was in the car had a p with two lines in the top corner and the one thats in there now has a kinda 'T' shape next to the p. it had all new discs and pads before i bought it, and ive checked them just now and the discs look new. plugs have been done, and the ones that came out looked ok, brown and not white, so its not running lean. dizzy and rotor arm are the next on the list, but its had a new stainless system fitted, so its not coming from there, ive gutted the cat, as i thought it might have collapsed. is there a chance it could be down on compression? will there be any tell tale signs if it is? or will it just run like a bag of shite? i have also noticed when i was setting up my grainier valve that fuel cut seems to occur just before .9 bar on my gauge? i thought it was just after @ .93bar? also, manifolds, i know theyre prone to cracking, so i need to check that again, but is it likely to be much louder (exhaust wise) ifits cracked? as i had my standard system on there untill a few weeks ago, and it was quiet as a mouse? any other things to check would be good? might check my bov too. the turbo appears to be in good shape, as you get a little haze out the exhaust when its first started, but after that its perfectly clear when booting it. plus very little signs of oil in the tmic. any help would be great as im feeling real shit about this now. i want my quick glanza.
