Q: Loss of engine power when driving over 50 mph

asked by on October 18, 2016

I have a 2007 Ford Mustang gt with 177000 miles. I drive 150 miles a day round trip for work. While on freeway I noticed that it felt as if it were pulling back as I was driving. No change to rpm or speed, just more of a feeling like tug of war. I put in new plugs and seafoam to had but didn't help. Last night it got so bad I dropped from 75 to 35 quickly, heard a pop and this wrench icon appeared on dash. Pulled over, turned it off, turned it on and it seemed fine, provided I didn't drive over 50 MPH I took back roads home. What is going on?

My car has 177700 miles.
My car has a manual transmission.

I have questions about my 2009 kia spectra's CEL and the codes I had read. Car run's good and was running good when light came on.
