CEL, no boost, whining noise Posted by ccb056 [Email] (#1568) [Profile/Gallery] (more from ccb056) on Sat, 22 Nov 2014 17:18:21 Members do not see ads below this line. - Help Keep This Site Online - Signup |
1991 SPG with oil cooled garret from late 80's 900.
Was driving along the interstate spiritedly, heard a whoosh noise, and lost all boost, the CEL light came on immediately.
Pulled over to look for split/disconnected air hose, couldn't find it.
Car runs, CEL light is on, does not boost at all. Have to feather the throttle and accelerate very very very slowly to drive without whining. If you get into the throttle even the slightest there still isn't any boost and it just whines.
No smoke nor funny smells.
Going to let it cool down overnight and take a look tomorrow.
Will pull off intake hose and inspect compressor wheel for play.
Any ideas?
Leak in intercooler?
Turbo bypass valve?
Idle air control valve? (have been having an intermittent fast idle the past few weeks)
