strange omega

my omi has macken again n few new beautiful things that occur with my omi: -motor turns after cold start in stand at 2500-3000 rpm, settles after 5 min drive -motor is after cold start off -12 degrees and worse strangled. stays running only when after let every amount of gas is given. -tanker needle shows overfull. shows on “10 clock” !! or just stays down in red. -jetz the most beautiful: with strong spring (beat hole, floor wave) I hear a strange noise. ic h describe it as follows: sounds like if you have glued every amount of ice directly behind the wheel to the speller and that then sits on the floor and so naja crawls but not so scratched. wees real ne as I should describe it. sounds however partly quite dangerous. as if something was sitting up. but I already looked at everything freely below. had such an idea that like water has penetrated into the shock absorber and is frozen. and when it dives this noise arises. or kan n the ice to be in the spring plate? everything sounds pretty stupid but I know really no where it comes from…. PLEASE HELP !! thank you
