2004 Mercury Sable LS 6 Cyl 3.00L
Car jumps and hesitates
A few months ago my car mercury sable started running rough and jumping when I pushed on gas, now it does it when I have brake on also. It was misfiring according to computer so I had a coil and spark plugs changed, it was a little better now way worse with jumping and hesitation. Doesnt want to go and then when I push hard on gas sometimes it kicks in and takes off but still runs rough, according to computer scanner now, it has code po193 which is Fuel rail pressure sensor circuit, high input. Somebody told me it may need fuel pressure regulator. I cant find one at auto parts store, was going to call dealer tomorrow. My daughter is doing all of the work, just wanted your opinion. Car has 84,000 miles. Thanks
First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance.
