OK, for my 16th birthday i worked a deal on a 90 NA with 150,000 miles. This guy that i bought the fc from NEVER reved it past 6 grand. Before he had the 90 fc he had an 87 with 300,00 miles...on two different engines, but i told him that the car is losing power. He said that he replaced the throttle body positioning sensor and the power was restored? I havent ran a compression test on my engine yet but i was wondering ways to check if the sensor is bad. My friend with an 86 fc drove mine and said that the throttle wasnt as touchy or responsive as his so...If anyone has info on my problem, please post it. Thanks

Brad
