Check your owners manual but I'm pretty sure fuse #1 in the distribution block under the hood is not used.

Not too long ago, I had one of my vehicles in the shop for work (not my Mustang). Even though it didn't involve the A/C, they had to discharge the coolant. I'm assuming it was because they had to move an A/C component out of the way. Usually they can capture it and refill it. Any chance they had to discharge yours and forgot to replace it?

The manual said the fuse name is engine #1 I forgot the actual fuse number ... As for discharging the a/c the said they only touched my transmission and that one o2 sensor they did nothing with the a/c

In another attempt to see if it's my tune causing the sensor error I ran my tank dry and filled her up with 93 octane fuel and loaded my 93R tune ... Not taking advantage of the situation or anything lol drive safe everyone! Will update if the CEL comes on again ... If not then I've found one awesome cure

Update so far

Found out my "engine #1" fuse controls my egr evap control and o2 sensors so I bet the o2 sensor the mechanic put in had a short which caused the fuse to blow which is causing my CEL so after work today I will be visiting him and the owner to have a nice discussion about my findings and hopefully get it replaced with a proper and functional o2 sensor and fuse
Not sure if that is also causing my a/c to stop blowing cold

Sorry to hear you are having to go through this. I recently had to replace my whole clutch assembly and experienced no issues. I had to get used to the clutch grabbing really low and also the clutch pedal is super light to push down.

Does your clutch pedal feel alot lighter than your original?

One minor thing they forgot to do was plug the brake connectors back together and my brakes weren't working. I had a lady speed up beside and me and was nice enough to yell at me. LOL I took it back to the shop and 30 seconds later all is good!

Hope you are able to get everything resolved, at their expense!

Update

They removed all o2 sensors and the fuse is still popping so I get to come back tomorrow for another crack at it.

@kevin
Yes at first the clutch was VERY light but after around 100 miles it's been tightening up

Good to hear they are working with you and trying to resolve the issue.

I was told the pressure plate was revised, to lighten up the clutch pedal. I am starting to feel the clutch pedal tightening up a little, which is a good thing. =-)

With the new clutch, do you feel the car pulls as hard?

Keep us posted!

@kevin
I didnt put an oem clutch in so i cant really compare I put a precision performance clutch assembly in clutch pressure plate flywheel slave and TO bearing ... It is VERY grabby...it doesn't slip under any condition as soon as I hit the friction point it grabs hold and im in my seat

And yes they are working with me but getting it fixed is a better solution lol

I had to replace out everything you listed above as well, but I went with the OEM. The sport clutch quote was a good bit more.

Getting it fixed would be the best solution, I hear ya man! LOL
