POWER DELAY W203.045 mod:2000 kompr.

Hi the all,
After rear SAM replaced,new problem in the car,(nothing to do with SAM) .When you try to accelerate,no instant power, comes always after 5-6 sec ,and like a limp mode,or like no boost from kompressor .Undriveble!This is happening 8-9 times to 10 .But once to 10 , work perfect.EOBD tester kept codes P0101,P0102,P0301,which droves to MAF( low voltage,no:1 missfire..).No TPS error code .MAF replaced with a brand new equivelant, from LOWE Germany(MAF Hot film specialist. Before this, an unpluged OE MAF test applied, and the problem remained the same.After the new one, the engine rev perfect for a minute ,soon after the same problems.So MAF is not the problem.Except an oily cam magnet connector(cleaned),all other sensors seems ok,with a first look. Any suggestion before i go deeper, and try to get a STAR diagnostic??!!.(Mercedes must offer a star tester for FREE,with a w203 sale!) The car has strictly,20k miles only since new,and this seems another weak point of w203 electronics.-
