Okay I have a 2000 v6 mustang 97000 miles with serious lag problems. I'm talking a prious can take me off the line. I have 3.73 gears in the rear, cold air intake, a sct power flash tuner, I run 91 premium octane gas. I have a new fuel filter that I put in two days ago. Ran sea foam in my gas to clean my injectors and what not, also have had a technician at a Ford dealership look at my car as well. I had read an article concerning my balancer so I had bought and replaced that as well. Also tried putting a msd coil pack and still...... nothing has solved my lag issue. We can not seem to find the d*** problem! Please help! Any suggestions!

 

Welcome to the forum Clayton. Sorry I don't have any help with your problem. It would be a good idea to post this in the "SN95 Mustang" section of the forum. There are a lot of good folks there that may be able to help. Good luck.

 

Numerous things come to mind, Air Filter, Throttle body needs cleaning.
Does it only do it on takeoff and run good the rest of the time?
