When I first bought this talon from a friend (which sat outside for six months), I changed the plugs and saw carbon buildup on the otherwise good plugs. I got an injection cleaning done at a shop and suddenly the car wouldn't start. The mechanic got it running and said the throttle position sensor needed to be cleaned or replaced. I broke it on accident so I just got a new one. Now my car is sitting in the driveway and won't start for more than a few minutes if at all. When it does run, it sputters and will stall if i even slightly touch the accelerator. I bought it as project for this summer, but I need to keep it running until then and have limited funds at this point for a mechanic. What might be wrong?
