855 GLT light turbo. 58k, 60k service performed about a month ago. Action: switched from economy to performance. accelerated slightly,engine bogged,engine check light came on. Bogs at any but slightest throttle. Will die in neutral, maintains idle at stop in Drive. Will accelerate smoothly at very very light throttle. Cruises smoothly up to 60. Seem to hear a light whistling sound (like blowing over mouth of a bottle) sometimes while moving. Picked up car from body shop this am, drove 15 miles or so to work, no problems, problem began after another 5 miles or so. Replaced radiator, condenser, front core support. (radiator mounting tab broken, condenser lightly dented).. So various hoses and wires were removed to effect those replacements.
What might've been left unplugged, or loosely attached to cause this problem? Any suggestions? Taking car to dealer in the morning to pull fault codes.
