I was having the same hesitation and bogg problems, I followed these instructions and changed the plugs....all clear!!! No problems whatsoever. Thanks for the tutorial, this site is awesome! I consider myself a rookie DIY mechanic, and these instructions were perfect. Thanks again. celebrating now with a cold one <img src="/forums/images/graemlins/cheers.gif" alt="" />

I did it, too, and the car runs MUCH better. I'm just not sure how much performance improvement was due to the TB cleaning/mod and how much to the spark plug replacement. But this was a good excuse to buy a Dremel kit. <img src="/forums/images/graemlins/lol.gif" alt="" />

The plugs were well worn after about 50K miles, so they needed replacement. The gaps were anywhere from .05 inch to about .06 inch - pretty wide. I looked in the air tube and the TB and ground off any metal that interfered with a smooth transition between the parts (it wasn't much but we want to remove any unwanted turbulence, don't we?). I also smoothed the tube where it flares and goes into the TB.

Let's face it, our engines aren't gonna have a lot of push at lower speeds. But any improvement will help.


Paw-paw Don, y'all

Yeah...and is it possible some of the improvement might be subjective too...but anyhow, I like that and since there is no harm doing it, and I already have the dremmel <img src="/forums/images/graemlins/pfft.gif" alt="" />, I promise I'll do it too on my next pass in that area... even if it turns out just for the elegance of the air flow, and take the "before" photo that is missing above.

What is the Black Box you removed from the intake tube?

Thanks

Very Nice!

A few observations: If you do soak the throttle body in carb cleaner I would NOT let the TPS get saturated. The carb cleaner could damage it. Also with regards to the TPS: it would be best to cut off the electrical connector and solder the wires directly to the TPS. That connector is notorious for developing contact resistance.

Unless you plan on porting the throttle body like you did I wonder how necessary it really is to remove it completely to give it a good cleaning. I just open the plates and clean them with carb cleaner at every plug change. Seems to work fine.

None the less...very nice pictorial. <img src="/forums/images/graemlins/kewl.gif" alt="" /> Do you want me to sticky it as a maintenance item?

wow its been a while, if you look at the intake manifold it has a tube off the trhottlebody that goes across the motor. in the middle at the rear of the engine is a black box attached to the tube. its an air silencer. it makes the intake quiet. basically it means it interupts the air flow to the throttlebody. take this out and plug the hole and now you have more air to the tb. more air = better performance. the engine is an air pump so when you do a cold ait kit or ram air and the stuff in this writeup its a good idea to upgrade to a 2.25" exhaust.

Wow!

Been a long time Don!

How the Hell is turtle?

As far as that black box---just seal it with some plumbing cover with a clamp---and it should be good to go! <img src="/forums/images/graemlins/kewl.gif" alt="" />
