Sveiki ,
vienas draugas iš Norvegijos paprašė papostinti jo tekstą čia , Lietuvos Audi Klubo forume , nes žmogus turi ledą Audi 100 Sport 2.2.TQ ir niekaip neišsprendžia problemų su varikliu  

"Early this summer my 1990 Audi 100 TQ Sports started to misfire when I first started it in the morning. I had to rev it at about 2500-3000 rpm for like 10 seconds before it fired on all cylinders. At the same time it started to misfire occasionally when the turbo was boosting.
The latter problem got worse to a point where the car is now undriveable. It even misfires before the turbo kicks in.
The spark plugs were checked, and the car runs very lean; they're white as snow. I've also checked all kinds of hoses,
I can't find any leaks anywhere. I've checked voltage at the fuel pump, that's 13,64V. No errors on the fault memory.
It boosts 0,85 bar of turboboost.

All sensors, hoses, injectors, gaskets/seals, ignition parts are new, new spark plugs (Bosch WR6DP), new Bosch 040 fuel pump.

Before the engine started to misfire I hadn't touched anything. What could be wrong?"

Kas turi kokių protingų minčių ir galėtų žinot sprendimo būdą , prašyčiau pagalbos
