First of all, it worked pretty good. All the stickiness in the gas pedal is gone. This improvement is both noticeable and welcome.

I strolled on over to Advance Auto Parts and picked up a can of Gumout Throttle Body Cleaner. Total cost: $2.13.

I took off the air cleaner cone and disconnected the clamp that holds the MAF to the throttle body.

Here I encountered my first problem: remove the MAF entirely, or try and keep it out of the way? I opted for the second approach, which made access to the butterfly valve possible, but a little more awkward.

So I had my friend - he knows nothing about cars - start the engine with instructions to just keep the car running if possible.

I sprayed the cleaner into the mouth of the TB, and then tried to manually work the throttle - kind of tough to do with the MAF in the way, but not really a big deal.

What was really difficult was opening the butterfly valve wide enough to feel like I was actually getting a good stream of cleaner into the "meat" of the TB. The engine, of course, was revving way up, more than I was really comfortable with.

I followed the 10 second spray/10 second idle directions printed on the can.

Even with my friend sitting in the car, it was tough to keep it running - it must have stalled out a good 10 times or so.

On a few occasions, I just left the car off and opened the butterfly and sprayed a bunch of cleaner into the TB, then waited about 30 seconds and then restarted the engine.

I used the whole can, as per the instructions. Reconnected the MAF and air cleaner, washed up and then took it out for a 15-minute ride.

I suppose there is some difference in acceleration or performance - not a huge improvement, but it does seem a bit better - but the best part is that the stickiness in the gas pedal is 100% gone. This itself made the whole process worth the effort.

I'd be interested in hearing anyone's comments or thoughts on my experience.

I used Ford's TB/combustion chamber cleaner. I first sprayed all the crap on the TB, butterfly and behind the TB with the engine off. I then started the car and let it settle down before spraying some more cleaner to make sure everything was flushed.

Per the instructions, I clamped off the IAC hose and sprayed with the TB cracked until the engine was nicely loaded with the cleaner and finally stalled. I then let it sit for 20-30 minutes to give it time to dissolve.

Afterwards the car seemed much more responsive than with the TB cleaner alone. Next time I'm going to take the intake plenum off and give everything a thorough cleaning.
