96' Audi A4 1.8 SE stalling, power loss and rev dropping

when ever the car is idle the revs drop.

i mean dont sit at for eg 1100. they as far as to cut the engine out some times

it looses power on take off etc

iv replaced the MAF and claned filters. i also cleaned out the throttle body… its till doing it. the thing cut dead pulling in to 4lanes of on coming traffic… its gonna kill me. any feed back?

ps. im gonna replace the throtle mec completely tommorow
