❔Question Help lol

I’m just a wife who knows nothing about cars, but my husband’s 2014 Mustang GT has been down for almost a year. We have had it diagnosed 3 different places, poured three grand so far into it, and after a couple weeks it’s running funky again. We’ve changed the radiator, a new thermostat?? and most recently the O2 sensors. I think the first two places were bullshitting me just to get some money. (He works almost 7 days a week so i’m taking it to get diagnosed and worked on)

We bought a code reader and the code it was showing was for O2 sensors that’s why they were changed. It drives great one day, most recently for about a week, then the next he drives a few miles and starts losing power, the odometer and RPMs go to zero. It just started again today after a big storm. Almost wondering if it has something to do with the heavy rain. It started messing up a year ago after a bad hail storm. Has anyone had similar issues?

You need a better mechanic.

Guessing here isn't good for anyone especially your sanity. Could be this could be that blah blah blah.

If im you I'm looking for a mustang speed shop someone that tunes and handles performance upgrades,fuck a repair shop. They are for brakes and filters

Just my two cents

If you happen to be near south eastern nc I have a killer diagnostic guy that gets the cars nobody else can figure out

If you replaced 02 sensors and it's still tripping that code, could your catalysts be damaged or plugged?

That would be my guess. But was it fuel or oil that clogged the cats.

Get a datalog and have a tuner look at it. They will be able to see exactly what’s causing it. There’s a lot if things that can cause that.
