[QUOTE="toomanytoys, post: 16332801, member: 112770"] I know it’s not a mustang but it is a ford product (2003 mercury sable 3.0 dohc) and I can’t seem to get it running right. I am hoping the members here can help- Here’s the problem- the car stumbles when you first step on the gas like pulling away from a traffic light. Sometimes it even gives off a lean miss pop through the intake. When driving with light throttle the car runs fine. If you hit the pedal hard like when getting on the expressway the car falls on it’s face. Back off the pedal and hit it again and sometimes it responds I found some minor vacuum leaks and repaired them. I changed the pcv, fuel filter and the fpdm. I verified fuel pressure at 38-42psi at idle. The car has no codes pending or showing. The stft is at -1.6 on both banks but the ltft is between 10.2 and 11 What else could it be? The car has 62k on it and I bought it new so I know it’s history. Clogged injector? Fuel pressure sensor? I need to get this old girl running right [/QUOTE]
