That's interesting because he specifically said to me that if I had an auto it wouldn't be happening. Do you notice it right at start up?

Dealership called and said car is ready. Guess we'll see what the results are

Drove to car after work stopped here and them for food & groceries. No CEL for all cold starts so far... **knock on wood**. Really hope that ECU complete reset + Fuel system cleaner holds up! If so, I'm gonna start grabbing some parts haha. **fingers crossed**

How many miles since the Ecu clear + fuel cleaner?
I picked up my car. Thank GOD the technician was respectful and didn't mess with anything. Only put 2 miles on the car. I have a dash cam so it recorded everything and I have no complaints. He even used the fender liners.
Anyway, for my car they ran some diagnostics by hooking it up to the computer. He seemed to do research on the computer. I don't know what exactly was done for the troubleshoot. All I know is the actual work that was done is they replaced the 4 spark plugs and cleared the code. Work order says they also did pin point test. Anyway, the one person on here that had their problem go away was speedprotege and it was after cleaning his spark plugs. So hopefully it doesn't come back.
When I put my code reader in, it still detected a P0300 but the monitors were flashing so I dont know. There's no CEL on the dash. I'm going to put 100-200 miles on it and see if it comes back or not.

Roughly 200 miles. I'm actually going to scan the car right now. Let's see if anything pops up.
Do you know what plugs they replaced your stock ones with and @ what gapp?

I'm assuming just stock ones? I have no clue actually he replaced all 4 but it doesn't say what kind or what gap. If it solves the problem i'll find out more details

Did a OBDII scan, no fault codes on reader or on dash. However, EVAP system was incomplete as well as 02 sensors. I guess I still need to drive it more?

FYI: my cel came back on last night as I suspected after putting about 50 miles on it. It was after the 3rd start as I was warming it up. I'll be surprised if it's as simple as changing the plugs, but keep us posted, those of you who've done that. I plan to drive it as usual until I hear from my dealer with Ford's fix. Not gonna stress about it.

Picked up the car from the dealer today. I was told by the service advisor that no attempt was made to repair the CEL because, OASIS says not to troubleshoot. This was my third time taking it into the dealer for the CEL.
I also reported the squeaking of the brakes on the car and they are going to replace the brakes once they get the parts in. They say the parts are backordered for another month. Let's see how that goes! They had my car for five days and didn't even bother to diagnose it!
This is the most disappointed I've ever been with any car purchase and I've purchased a lot of new cars. I purchase a new car about every two years. This is probably the last Ford I will ever buy!

I can absolutely understand your point because the poor quality some dealers are showing together with the poor quality of the car FORD did deliver is a shame. I know that in the 80's Ford had in Europe such a bad reputation in quality, especially in rust protection, that nobody really bought a Ford. The Mustang brings old memories back, I thought, would stay in the past.This is the most disappointed I've ever been with any car purchase and I've purchased a lot of new cars.

All talk that the 2015 Mustang is a change in model and a new engine is OK. But dealers should step up and treat customers like customers. Most people today forget who is keeping them in business.:amen:

Hey guys since the ECU Reset + Fuel System Cleaner + 94 gas I have logged over 350 Miles. CEL has no come back on. I strongly believe something in the fuel system (or plugs etc) may be causing the CEL's. Give it a try, it may be worth the few bucks & time to pull the battery for 5 mins or so.

Thanks. My fuel tank is almost empty so I'm going to run a bottle of Chevron Techron through it for safe measures. but I put on 85 miles since I picked up my car from the dealer after they replaced the spark plugs and there's no CEL. Still too early to say..
Does your code reader show all the monitors to be ready? I drove a solid 50 miles yesterday both city and highway
