audi quattro coupe type 89 runs not well

Servus people, I have a problem again and I’m in despair just a few days ago. Since a few days (weeks) my beloved Audi doesn’t run really funny white but only Wen he gets warm. That means so much the whom I turn him on in the morning he doesn’t vomit and runs almost as before only about 5 minutes later he doesn’t turn up high from Ca 2500 u/min. Motor is a 2.3l with 136 ps. But if he gets on 5000 tours it goes hugely forwards. I am with mem latain at the end. Exchanged pressure driver (no improvement) temp feelr (no improvement) lambda I checked as well as control current At the printer too. The again falls around so warmer he gets mistakenly on zero and can’t be set up Dan either (probe white tried Hmm I think I have now everything thanks you already in advance Mfg Ps: sorry because of the writing method is just from the phone out.
