What is causing misfire on driverside all 3 cylinders?

Asked by jeffro33 Feb 06, 2015 at 09:54 PM about the 1996 Ford Mustang Convertible RWD

Question type: Maintenance & Repair

Starts fine sounds like no miss for ten
seconds or so. Then difficult to keep
running. If I floor it, it's delayed but I
get more power than 3 cylinders. I've
replaced coil pack, plugs, wires, cam
position sensor, ecu, o2 sensor bank
1-2 which is still stuck at 1.25 like old
one. No codes 175,000 best guess I'm
stumped please help

I still don't understand how that would effect the one and opposite side only. Blocked cat would effect the whole engine I believe. Thank you for helping I appreciate it
