Spray brake cleaner or ether around every vacume hose you can find, around the manifold, throttle body etc etc. Failing that remove the afm check it is not bent or damaged. also check it is the right one for the computer you have.

The extra air going in leaned it out to a more suitable mixture. Normally its the other way around, the car starts to run poorly when you remove the oil cap. what have you stuffed around with to run so rich? If you're really serious about turbo just go MAP, its what most of the aftermarket ECU's run. a few people have converted from AFM to MAF but mostly NA engines running a piggyback computer.
