no codes or check engine light, I'd wish it would respond as if it were a stick , Is it just the fact that it's an automatic , that it feels that way? :?: Alot of the mustang sites suggest after market throttle bodies like bbk or accufab to inprove the throttle response, what you think?And thanks for getting back with me, I really appreciate it. :mrgreen:

So basically you're just looking to hop it up?? If you're going that route make sure whatever you buy is calibrated to work together and with your existing engine control system, some kits include new pcm parts.. if you just throw stuff on it, you're looking for problems where engine control is concerned, even something like a cold-air intake can present issues, not always but I've seen enough posts aroung the web on it.. also if emission testing is required in your area, aftermarket can create headaches with that if not a calibrated system... Check Ford Motor Company's website I know they sell factory hop-ups for the new Mustangs that work in conjunction with the oem pieces..

Suggested Repair

If modifying for better response, use a calibrated performance package that works with the existing engine control system, preferably Ford factory hop-up parts. Avoid installing unmatched aftermarket throttle bodies or intakes that may not match the PCM, and consider local emissions requirements.

Conversation Summary

The owner of a 2004 Ford Mustang Mach 1 automatic reports sluggish throttle response around 30-45 mph, with no trouble codes or check engine light, and asks about aftermarket throttle bodies. The expert advises using matched, calibrated upgrades that work with the OEM engine control system, warning that uncalibrated parts and intakes can cause control and emissions problems, and suggests Ford factory hop-up parts.
