Which will cause lazy valves and sluggish acceleration. Start with a seafoam treatment and then you can eliminate a dirty motor from the equation

Mobil one oil is good (enough) oil. If he keeps regular intervals it should be clean.

My car has only 39,000 to date and it did that issue about a year ago. All you need is ford or some one that can plug into your obd 2 to check out the codes. It's worth checking out.

So just go to the Ford dealer? And how bad was your throttle response? Just slight laggy or worse?

autozone/etc will read codes for free usually, write them down (dont just listen to what they say it is) and post them

It was pretty bad. The rpm would waiver back and worth during idle and some time it would just shut off. That happen after I hadn't taken care of it for along time. But high rpm it was ok.

Ya mine doesn't do any of that so I think it's fine. It's just a really slight lag. It's not instant that's all I'm saying but I think with these newer mustangs the throttle won't ever be instant.

Also I use my tuner and auto zones tuner and no codes came up. It wasn't till I brought it to ford and they plugged there laptop into my obd 2 the codes or what ever came up for them. I got it done for free because I know the guy but ford may charge you.

Another reason I prefer older vehicles. Drive by wire in my mind is an accident waiting to happen.

I 100% agree with you, @Revvv! But that link I just posted is at least a promising solution to this problem. I wish I had seen it 11 years ago when I got my '05.

i have a 2005 gt with. lots of bolt ons plus ford racing intake, mutha thumpa cams, shortie headers with off road pipe. 410 gears. bbk throttle body and spacer. steeda cai also a steeda custom dyno tune. i noticed some hesitation after 2500-3000 rpms after i put the cats delete on exhaust. but overall the cats delete made a noticeable difference compared to stock catalytic, just confused about this hesitation issue.

Custom dyno tune by steeda.ca
320 rwhp
266 rwtq.

No worries, my car is older than this thread so it still applies.
