1.8T jerks (LMM, ignition stages, throttle valve)

Hello, my 1.8T has been jerking since recently. Here’s the very exact error description: 14 days ago he didn’t jump on after a short stop (5min) with warm engine. Only after I gave a bit of gas when I started it went on and then had about 2 minutes of strongly fluctuating stand gas, after that the stand gas was constant. That with the not jumping occurred then opener, I always gave some gas (as above) and could drive. Until today, if I started the now (engine is still warm) then the stationary gas does not stop to fluctuate and when I take the gas away it goes out. I used to dig intensely google after the problem. The following things could apply: – defective air mass meter – defective at ignition stages – throttle flap flat. I changed the spark plugs today (they had it not) but the problem is still. Did you have a problem of any kind? How can I exclude something? Can I check the wound coils? Thank you And bye Andre
