Hi.
My Taurus has been acting up lately.
It has been driven a lot more recently.
Coming home from work last night, I had no power. I barely made it to 60.
It was a tough 18 miles on an 80 MPH freeway.
I got off at my exit, it started bucking & barely moving.
That's when the check engine light started flashing.
The engine temp started to rise also, it made it up to 210 degrees.
Oil, tranny & coolant fluids were checked, all good.
Could this be a fuel delivery issue?
The fuel pump & filter were replaced last fall by Ford.
I am at a loss here as to what's going on.

A thought, have you checked battery voltage. Sounds very similar to my grandson's 500 when the alternator died and he ran it until it would go no more.

Hi, I did drive it again, the flashing Check Engine light started right away.
It did kick out codes this time.
P0303, P0304, & P0305
It is a misfire issue.
BTW, it has only 67K miles on it.

Blinking light is a bad misfire and likely from a bad coil. Don't drive it in current condition or you will definitely destroy the cats and have a really big dollar cost repair. What is currently a ten minute $70 job will turn into a $600 plus job.

I ordered an Accel Super Coil replacement pack.
BWD was out of stock at both places.
I have had good luck with Accel in the past.
It was cheaper than the Motorcraft version.

There is a reason why people suggest Motorcraft or BWD, myself included. I have not had any experience with an Accel coil in the 22 years of driving, but cheaper coils are usually cheaper in quality too. Hopefully you won't have any issues, and didn't clog a cat. How long have you been driving with the misfire?

At least is starts now.
Something else is wrong now.
I am sending it to Ford for repair.
I am done working on this!

Hi John,
It started on Thursday as a slight miss.
Friday it was bad, I parked it.
Monday I changed the coil.
It at least started & didn't flash the Check engine light nor did it kick out any codes.
I think one of the brittle vacuum lines broke.
It's in for repair now.

I got it back today.
I made it 2 miles & it died.
The dealer sent a tow.
When I talked to the service advisor, he said all further repairs would be free.
I did get to talk to the tech who worked on it & gave him some insight into the issue.
There is hope my message made it to them.
At least, this time they gave me a 2018 F150 loaner.

Hello everyone,
The problem was a bad Cat.
One was plugged.
This was caused by a bad fuel regulator.
Thank goodness I found a reputable muffler shop.
They only charged me $350 to replace the front one.
I pick it up tomorrow, we shall see what happens.

My thoughts is the dealer charged you for an easy to reach and replace fuel injector and sent you on your way. The bad coil killed the cat based on the codes you posted. No rich mixture codes and just misfire codes. You are lucky the rear cat is still good based on you had a rear bank misfire code. What was your cost for the dealer troubleshooting and injector replacement?

Usual sequence.
Ignition like coil, wire, plug.
Then the cat fails if you drive it that way.
Replace the cat but then the coil and any other ignition parts.
Ford coilpacks are a weak part. Many of us have been there.

Hi Automender,
It was a bit over $700 for the fuel regulator, plugs, wires, & some vacuum line replacement.
The dealer shop rate is one of the lowest here.
Only Fleet Farm is cheaper.
After the Cat replacement, my car is back to normal.
It feels weird after not having it for 10 days!

Was it a fuel regulator or fuel injector? You originally posted fuel injector.

Hi,
It was the vacuum fuel pressure regulator.
The one you can easily see on the right side.
I will be adding another Ford to my stable on Tuesday.
It is newer & a lot bigger! :)
