24seven 104 Posted June 27, 2007 so from cold, start it up, it idles fine for a few seconds the cuts straight out. apparently it doesn't do this once warmed up, but it's not my car and I've not driven it. the owner (brother's GF) took it to a garage and was told the vacuum system needs replaceing . any suggestions what it could be?

welshpug 1,627 Posted June 27, 2007 XS = 1.6 8v TU, XSi = 2.0 8v or 16v, being phase 2 most likely 16v. idle valve/stepper motor problems are common on them (all engines!), but I havent a clue what they mean by "vacuum system" Share this post Link to post Share on other sites
Sandy 189 Posted June 28, 2007 Could be an air leak. Try another Lambda sensor. Share this post Link to post Share on other sites

RossD 43 Posted July 2, 2007 it will be an xsi if its 1.8 16v Nope, the later XS's were 1.8 16v. The earlier ones were TU 1.6 8v. The XSi's are either 2.0 8v (Phase 1) or 2.0 16v (Phase 2 onwards) Share this post Link to post Share on other sites
