My 100Q has no power again,,, big cow..

[Denis]

  I tried to get fault code but something i dont do or missunderstand procedure (in english) cause i cant get any engine light blink or not......

  I look at Bentley book for 5000TQ , even i have a 100Q 89, to see something i can diagnostique.

  The problems listed for my car is:

  7; Diminished or insufficient power
  1:Engine start poorly when cold
  2:Engine start poorly when hot
  3: Rough idle during warmup
  4: Rough idle when engine is warm
  .
  .
  .
  The thing that bind all those problemes issssss    differential pressure ouside tolerance, gray module....

  When i move the fuel distr the engine wants stall..... then i put it back and the engine wants to run again... 

  I checked for leak with Ether..... the engine accelerated when i shoot ether close to the intake manifold...... i removed it and reseealed it,,,, now no leak there and i did not saw any other leaks.


  Analogy: Mmmmm go to see a doctor and tell him i have all sympthomes in your book doc....... do you think he ll believe me ? hehehe

  Ðenis

  The fault code procedure is: (what i have undrestood)
  turn the key on, plug a fuse on the fuel pump relay for 4 secondes , then i can see the engine light flshing to show me the code..... this computer should speak to me :-) and tell me whats wrong hehe.

  It might tell me '' the problem is located 18inchs beside the steering ''   :-O.

    Hmm, if the compression feels low, you might run a test.  If the #'s
    really are low you might check your timing belt and verify it hasn't
    skipped a few teeth.
