Hello all
I'm having this issue with my 2007 V6 Mustang. As I'm driving on the highway when I drive over 80mphs my car begins to putter and my check engine light(yellow) begins to flash. When this happens I've been letting go off the gas for 15-20 secs or so and the light goes off and I have accelerating power again.
While this happens if I try accelerating the car just putters and it feels like it has no power.
Here's what I've done on it already:
-new coil pack
-new spark plugs
-new spark plugs wire
-new air filter
-fuel injection cleaning
Also a week before this started happening I had a new harmonic balancer installed.
The original problem for getting the new coil pack, spark plugs, and wires was that I had a check engine light go on but not flash. I was having a misfire on cylinder 3 and 4.
After getting that's fixed is when I started having this puttering and light flashing.
Any ideas??
Thank you!
