96 GT studders and lurches at higher RPM

[jts1991]

Hey guys, im a newer owner of my first mustang. I noticed that when i am at the powerband the car lurches and studders slightly. I have tried running some fuel injector cleaner, and running 93 octane. I just bought the car its in nice condition it has 127k mi. I dont know if this is a common problem or not. Maybe im just inexperianced with 5 speed's idk. If i punch it at say 30mph in second once it reaches about 3k RPM it studders a little bit then at 5 when i personally choose to shift its a little worse. I know it has a new MSD ignition. I put a K&N hi flow air filter in it yesterday. The only thing i can think of to fix it would be maybe fuel filter is clogged?

You tried changing the spark plugs and wires yet?

i will concur on plugs.

check the condition of the plugs, wires, cap, rotor and coil... You could also unplug the MSD ignition from the harness and plug your factory
harness back in the coil and troubleshoot just to eliminate one variable.
