Hi all, As you can see my post count is very low, but I've spent a HUGE amount of time trawling this site! For reference, the car is a 100% standard '91 1.9 GTI with 56k on it. I've got a starting problem - on start up from cold the car will misfire and if you don't catch the revs, will cut-out. Taking the car to 2.5-3k rpm will get rid of the misfire and then if you hold the revs at c.1500rpm for a few secs will then stick at about 1400rpm which then drops to about 1100 rpm before the SAD closes up. At this point the revs will hunt between maybe 500-1200rpm, often cutting out when coming to a hault in traffic. Once the car has warmed up a bit, it'll run fine. The car originally ran nicely without issue. It all went wrong following a service which saw all fluids replaced as well as fuel filter, oil filter, air filter, plugs, leads, dizzy cap and rotor arm with the throttle body, SAD, hoses, and AFM all cleaned out at the same time. Since then I've tried different leads, different cap, different SAD and new HT coil, none of which made any difference. What did work was putting the old plugs back in, the car started well and without misfire about 3 times before reverting to being a pain - does this indicate something is wrecking the plugs? if so, what could it be? Other things I know: There appear to be no air leaks - infact, before the car had starting problems it had a small leak at the sunroof T peice which was subsequently fixed. The vac advance appears to be working following the suck test the car cuts out as soon as the AFM is unplugged it cuts out when the CTS is unplugged I've tried adjusting the mixture screw to both extremes and everywhere in between with no success. I know this is a problem that has come up before, but like I say I've been through the site over and over and feel like I'm running out of possible solutions - if anybody has any ideas or is based in Derby and has some knowledge or bits they's be willing to swap over to test my more suspect components I'd be really grateful. I'm really annoyed at myself actually, its a fantastic, very clean car and my (well intentioned) service seems to have set it back some-what. http://s234.photobuc...ot%20205%20GTI/ Thanks, Will
