I have a 2001 Ford mustang convertible with dual flowmaster side exhaust. The car drives fine but when I am in 5th gear on the interstate or goiong up a steep hill, it starts to what I call sputter, like I have a leak, but I know I don't, I just had that fixed. What can I do or have done to fix this problem?

sounds like 5th is to high of gear to pull a steep hill, try a lower gear

Are your RPM"S getting to low to stay in 5th? I can't go into 5th and maintain a solid 2 1/2 rpm's untill i'm doing like 70-75 mph in my 01 mustang. Once it starts to drop below that it starts to lag and I have to downshift into 4th and it's fine. What tranny is in yours? Also, how long have you owned the car?

sounds like engne `lugging' that is you've fallen below useable torque in RPM range 5th gear is overdrive, you need to be at least hwy speeds in this gear. if you drop below say45-50 up a steep grade in 5th you need to downshift to lower gear to stay in useable powerband. watch your tachometer when driveing normally. feel the power & acceleration @ 2--3--4000RPM?Where is it when it acts up? if below say 2k= 2300RPM you need to downshift to raise eng. RPM to adequate powerband. try it you'll like it!

try fuel filter first also have your fuel pressure checked, the pump could be getting weak
