2002 mustang 3.8L cuting out
I tuned my 2002 3.8L mustang about 4 months ago. I put motorcraft plugs and napa wire on. since then I replace all of the plugs with autolite because the car started cutting out real bad when under a load. changing the plugs did not make a difference. I need suggestions on what could be making it cut out when I try to accelerate. when Idling it is smooth and shows no misses. What can be causing it to cut out when I accelerate.
