Engine really jumpy
 

K guys... heres the story the engine runs fine just riding along..when i hit the gas kinda hard and the turbo kicks in for boost the engine gets really jumpy like rpms are going up and down really fast like if the car doesnt want to run kinda....but when i let go and the boost is gone it runs fine and just goes along the road like no problem. Any ideas of what could do this? if you would like to know more details ill be more then happy to answer as best as i can.

THanks,
Nick

You probably have an air leak. Check your turbo hoses. My friends celica did this a lot, And he got a cold air intake and it was fine. And then when we looked at the old hose close (inside the house) it had tiny crasks all over the ribbed part.

Possibly a boost leak.
