It seems alot of BA's do this..
Mine is also in the same boat. Some days it never does it, other days it may do it at every set of lights. My uncle has an XR6 and he said that his does it too.
I will also clean the TB and go from there.

Funny because this was told to me and a close friend by a Ford Dealership.
And I was also advised that the fault didnt logg in the ECU. The ECU's are not very accurate. you lot trust in your ECU's to much and have lost your good old fashoned ability to diagnose EFI issues without refering to the "Diagnostics"

I'm not taking sides or anything, but just pointing out that xpression is a ford mechanic.

In reality, to clean your throttle body you only need a rag and some minor elbow grease.. If you take the throttle body off it will be EASY.. If you leave it attached, you'll still get the bulk of the grime off.

Just make sure to wipe every surface you can see.. Butterfly face and edges - front and back sides, the cylinder itself, and get in as deep as you can(if leaving attached)

I'd recommend doing the job properly if you're going to take it off, you don't want to round the bolts, get some good tools..

Eg. a magnetic screwdriver housing that will hold your hex bit, a 6mm hex bit(or is it 5?) and a 1/4in ratchet with a 1/4in socket to hold the hex bit.

Use the magnetic screw driver to guide the hex bit into the head of the bolt.
Use your finger to force the hex bit to stay in the bolt head, while you remove the magnetic screwdriver.
Get your 1/4in socket onto the other end of the hex bit so you can release the tension - getting the ratchet onto the lower 2 bolts is going to be tricky, but 5 minutes of messing around will save you alot of time if you rush and mess it up.
Once all the bolts are loose, go back to the magnetic screwdriver - it will be much faster to remove the bolts.

*Note* You may need to get another throttlebody gasket prior to doing this(or during)
My XT was sealed to both the throttlebody and the intake manifold which meant I had to force them apart, where as my Futura was simply compressing the gasket between the two so it came apart easily.
This meant it was easy to unbolt and reassemble on the Futura, but the XT required that I carefully scrape the gasket off the manifold and the throttlebody WITHOUT getting any of the gasket in the intake manifold.

If you feel your mechanical skills aren't upto it, just take the intake piping off, and clean the throttle body whilst it is still attached.
If you feel adept or want a challenge(regardless of how minor it is) I recommend taking the throttlebody off, it is easier to do a perfect job.

Good luck, enjoy the results!

i pulled mine apart today and cleaned it out, it seems to have more go, and ill let you know if the idle is fixed after i give it a good run, and also if the fuel econemy is back.
cheers rob

I also cleaned my throttle body today. Idle was fine today. When I reverse into my driveway, I usually put it in drive and move up again to the right and as its a steep driveway, its usually a little squirt of the accelerator, then straight to park where the idle always drops and makes the car shudder. Today, it didn't do it at all

I used some carby cleaner I had in the garage and it worked wonders, as I sprayed it, the grime started dripping off.

is there any logical reason this makes a difference? im doing mine this weekend

Well thanks guys I am gonna have to do this to mine now. LOL. Just started developing these faults.
Ha.

Is there any reason what makes a difference?

The throttle body builds up grime because the top of the rocker cover vents the excess oil fumes back into the intake to comply with ADRs(they can't vent back to atmosphere)

So unless you get an oil catch can (or filter it illegally back into the atmosphere) you'll always have build up. And in reality oiled airfilters probably contribute in a way also.



If you meant a does it make a difference taking the TB off, then yes, it does make a difference, but depending on hoe much effort you go to after taking it off decides how much of a difference.
Just cleaning the TB when it's off will render similar results to leaving it on..

Hope this helps..

Happy Motoring

sorry, i meant more does it increase the idle quality and acceleration THAT much? or just a bit?

ok. just got mine done and i think the ISC is dead. (thread about it here)

its almost like the isc isnt trying to find anything
