The throttle lag/delay was getting so bad on my car that I didn't enjoy driving it anymore. I took the throttle body off last night and cleaned it (after watching the Brenspeed tech video http://www.brenspeed.com/tech.html) and the car drives like new now. Wish I had done this sooner. Only took about 15 minutes to take the TB off, clean it and put it back on (not including the time to remove and replace the strut tower brace and engine cover).

 

That's something that I probably should do soon. How many miles did you have on your car when you did the TB cleaning? I'm at about 33,000.

Rich~

 

Around 38,000 miles. I should have done it at about 25,000.

 

whoa I have 55k on mine..... probably time to take a look at it eh

 

I just did mine at 55k. However, JUST cleaning it may or may not be a good idea... Awesome wasn't exactly a happy camper after I cleaned her TB out. I also wound up having to pull the negative terminal off for 30 minutes, then retrain her. Here's how the adventure unfolded:

Got home from a nephew's pool party B-Day celebration. Yay he's 5.

Pulled the air intake hose off. (two screws, one breather tube [watch that green clip thing])
Pulled TB off (easier to deal with, it's just 2 nuts, 2 bolts, and two electrical connectors.)

Ok, so now I cleaned TB with Valvoline Throttle Body and Carb Cleaner (I tried to find just TB cleaner, but it's made of invisible. o.0 ) sprayed, let soak a little, sprayed again, then rubbed the chambers with a cloth so it was as clean as possible.

Installed the TB back on the car, no big deal. Make sure, though, to get that orange gasket back in it's slot.

At this point, I started her up and... well, it was odd. She kept not throttling back. Hm. Maybe a little driving (I'm a n00b, sue me.) Oh, no, this 3000 Rpm hang up, while noisily cool, is not going to do in a parking lot. Time to retrain.

So I pulled the negative, waited 30 minutes, and then reattached.

I then did the throttle pedal retrain: Turn on key, wait for all the lights to settle, then push the throttle in slowly to WOT. Then release throttle, and turn car off. Wait 5 seconds.

I then did exactly like the Owners Guide said to do on page 204 (on mine, your OG may vary.) Turn on key, neutral (manual), park brake on, no accessories on. Did put the windows down, it's hot.

Turn on the car, and let it get warmed up. About a minute or two in this heat. Once at normal operating temperature, let it idle for 1 minute. The timer in the dash works great, btw.

After that one minute, turn on Max A/C. Idle one more minute.

After that, retrain your windows: Left side first, then right, pull window switch up and hold until it goes up all the way, continue to hold switch for 2 seconds past that (I do 3), then down all the way, holding switch for another 2 seconds after it's down. Repeat this process 5 times. Repeat process on right window.

Now, go drive for 10 miles. This gets it mostly figured out. I reset the trip and clocked it off.

Just to be sure she was happiest I could make her, I started out with 5 miles A/C off, then 5 miles A/C on, then another set off and on. I also did freeway, twisties and stop and go.

Now she's a really happy pony. Throttle responds nicely, no more dipping idle and hard to respond, and it's not hanging up at 3000.

I just wanted to be sure to relate what worked for me. In case it helps someone else. Good luck!

 

I just did mine about 3 weeks ago andd also cleaned and oiled my cai filter and only have 11,000 miles on her now, she runs better than ever now.

 

I cleaned my throttle body using throttle body cleaner and a small brush. The reason I used the small brush was I didn't want to force the throttle body plates any further open than they would go with light pressure. This allowed only a small crack to work the cleaner around with the brush then rinse with cleaner. I didn't want to put any pressure on the gears inside that throttle by wire system and disturb it's settings. I, myself, would choose not to follow that video unless it was a cable system.

 

If it did, I couldn't drive her now. It would have broke right away. I think it's safe. I felt how they work when I opened them... seems it's sprung, and made to open by a push lever system, not a gear, per se.

 

I have had no problems after cleaning the TB and opening and closing the throttle plates numerous times.

 

Call me Krazy, But I just went ahead and bought a spare from New Parts Takeoff. If mine needs cleaning, swap it out, comes with the TPS and clean the other one when I get to it.

 

I hope that works out for you. I ordered a set of takeoff rotors and I bet they had 5000 miles on them. I'm not sure if I would ever buy any electronics from them after seeing the rotors.

 

Got it in, and it looks brand new. Can't go wrong with that.

 

I'm not so sure I like the Brenspeed instructions for cleaning the TB.

It asks you to clean the butterflies etc with a towel.
I don't know if you guys are aware of this, but our TB's have a protective coating on them. That is why we are told to use ONLY a certain kind of TB cleaner that is safe for our TB's. (CRC brand it has a statement about being safe for these types of TB's).

The fact that Brenspeed does NOT point this out does not impress me
to say the LEAST.
The second part is I don't think wiping it down is such a good idea being as you can wipe the protective coating right off the **** TB.

I would suggest using the CRC TB cleaner, spraying the TB, and let it sit as the dirt/grime drip off of it.

I smell trouble for people who have done it the other way down the line.

 

That's odd.
Newtakeoff.com is only supposed to supply parts of cars with 5-10mi.
or less on them.

 

I have 65K on my '07 GT/CS and never cleaned the TB; my question is do you have to remove the TB from the engine or can I just remove the CAI and clean it that way? The less work I need to do the better as Murphy's law would have it I go to fix one thing and break something else. Any help would be greatly appreciated.

 

I took mine off to so I could clean the back side easier. I didn't have any problems taking it off or putting it back on.

 

The throttle body cleaning went just great with CRC. Car has 50K miles and badly needed it! Idle and low speed is much smoother now.

Bad news is I broke the locking mechanism (red piece and black tab!) on the electrical connector that goes on the driver's side (upper right hand side) of the throttle body. I have a zip tie holding it in place now. Any ideas how I fix it? I figure either get a new connector or a new harness (ugh!)

 

Good luck with just the connector, I dunno if Ford would sell just that. You may have to get that connector off a wreck in the wreckin' yard. It might be possible to just get the plastic connector off the harness, but you might have to clip that part of the harness out to have enough 'play' to play with it.

I'd probably, if I needed to, cut mine off and solder in the 'new' piece, hiding the properly fused and shrink wrapped joints under the harness tape/loom.

I hope I don't have to one day, though.

 

I cleaned mine today, along with the MAF and C&L air filter, and installed an oil separator. I used a microfiber towel and CRC throttle body cleaner to do the job. Everything worked out great; there was a ton of crap on the throttle body. While I was doing this, I disconnected the negative battery terminal so that the car would relearn the idle trim. I started the car up with no problem and the engine runs great. (I have 34,000 miles on my 08 GT).

 

And to think that a quality JLT Oil Separator and properly oiled filter can save this from happening in the first place. Or at a minimum, make the intervals MUCH longer.

Just my .02. Glad your baby is tuned up and getting down the road better!
