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

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

Remove o2 sensor on that bank and run engine. and see if that helps

Tried that (disconnected connector)ran much worse.

Did u unscrew it out of exhaust

No I didn't. That's passenger side sensor, shouldn't effect driverside.

Take it out than run to see if catalyte converter is pluged on that side

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
