Hi everyone, I just bought a 2001 V6 convertible Stang, and it's having a few issues and I'd like to see what y'all think. First off I had the P0401 engine code, which I've seen most people say is the DPFE Sensor so I went ahead and replaced that and sprayed some brake clean through the lines, but didn't help the rough run- and by rough run, I mean when accelerating and I hit around 30 Mph and it starts doing this weird bumping thing like it's kinda hesitating(honestly kinda hard to explain) then i noticed once when I accelerated the engine light started flashing which I know is a misfire but haven't had the chance to check the code on that yet. What do you guys think I should start with? I was thinking clean the EGR Valve and check my plug wires next to see if it helps and just wanted some input. Thanks for any help!
