Hey i have an 01 v6 Mustang that recently had been tore apart for new head gaskets and the other day I was on my way home and found my car stumbling and falling short on power it wouldnt go any higher than 3k rpms and was extremely difficult to get it up higher than 40mph the MIL flashed at me so when i finally got home about 6 miles latter i pulled the codes p0300, p0304, p0305, and p0306 any ideas why all 3 cylinders on the drivers side are missing my guess was coil pack but wouldnt i have misses on either of the other 3 cylinders as well?
