2001 mustang vibration at cold in reverse and first gear
I start feeling a vibration in my car when engine is cold does not vibrate in adle ones I shift to reverse it start to vibrate like a misfire (not misfire codes) I shift to drive and it does the same think in first gear after engine is warm or hot no vibrations not matter if it's on R or D
Spark plugs and spark plugs wires
Trans oil change, fix a p1518 code IMRC stuck open
And the vibration still happening any ideas what it could be?
