4FOR4 Posted November 8, 2004 Share Posted November 8, 2004 Looking for some diagnostic advise for the turbo of a 92 legacy sedan, auto, 2.2 Suddenly it doesn't want to go faster than 38 mph. When it hits that speed, the turbo sounds like its dumping and the engine sputters and sometimes stalls. Is the dump valve releasing too soon? What other controls should I check?

Qman Posted November 8, 2004 Share Posted November 8, 2004 Could be a few things. Loose hose in the intake system. Plugged cat. Could also be in limp home mode. Are you getting a check engine light or any codes? Maybe other things as well. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted November 9, 2004 Share Posted November 9, 2004 Yeah....is the check engine light on? If so, go to my site and you'll find instructions on how to pull the codes. You may also want to check out www.bbs.legacycentral.org as well. Quote Link to comment Share on other sites More sharing options...
