Hello, I have a 93 7. It seems to want to lose power when it isnt under full power. My "check engine" light came on so I looked under the hood. It seems that I had a tear in the rubber coupling that comes from the turbo "y" pipe. I replaced this rubber piece with a silicone part and I had full boost again... 12-8-10. The car was running like a raped ape!! But, still it wants to lose power every now and then? When it happens, i floor it and it instantly goes again? What could this be?
