Dub & David, why not make it three. I'm sure my car could use it too with all the abuse it gets.

May I strongly suggest another easier way to clean the intake manifolds?
It involves using injector cleaner fed directly into the intake manifold with the engine running.
Materials and tools needed. One or two cans of your favorite injector cleaner. A three foot length of vacuum hose that is just the right diameter to fit snugly into the intake vacuum ports on the top of the intake manifild just behind the throttle body. A pair of vice grip pliers to use as a metering device (I like the long nose type). An ordinary screwdriver or two.
Remove one of the two vacuum lines from the intake manifold by hold the retainer ring against the manifild with a screw driver while gently pulling or prying the fitting up and out. If you do this correctly the fitting should slide right out. Fit your cleaner vacuum hose into the hole and make sure it is a snug fit. Open the cleaner and drop the other end of the hose into the open container of cleaner. I like to sort of wedge the bottle of cleaner between the battery and the headlight support to keep it steady. Clamp the hose with the vice grips. Start the engine and allow it to stabize. Gently open the screw on the vice grip to meter the flow of the cleaner (it is a little tricky to keep the flow from getting too heavy). Gently increase the throttle if needed to keep the engine running. Don't allow the cleaner to go through too fast. Slower is better. When the bottle is half empty, shut off the engine and move the vacuum hose to the other port in the intake manifold and repeat the process until the cleaner is gone. Reinstall the original vacuum hoses.
If you want to see how well this is cleaning, before you start, pull the air intake tube off the throttle body and open the throttle and look at what you can see of the inner part of the manifold. After you are done, look again. And while you are there the second time, clean the throttle body. Follow up with another bottle of injector cleaner in the gas tank.
You will be amazed at how much better the engine runs.
If you still feel that you need to pull the manifold off for cleaning, try doing this first. It will most definitely make the job much easier.
This sounds too easy. It wouldn't damage O2 sensors would it?

Why not make it 4? Well I guess one of our cars should be running in case we need to go get some thing. I will enjoy drink a beer watching you guys do this.

No, the oxygen sensors are not damaged from cleaning in this manner. We do a similar process in the shop I work in using BG products. We do several cars a day.
In my days as a tune up tech back in ancient history when carburaters were still common, we often did a similar proceedure by spraying or pouring a combustion chamber cleaner carefully down the carburator while the engine was running.

Coke bottle trick? I think I will try this aproach as it is cheaper than replacing all of the gaskets.  Now if this doesn't solve my cars bucking I'm gonna be ticked.

Be aware that with the cleaning method Big Jim describes--which I've done several times--will only clean the primary runners if you don't manually force the secondary butterflies open. Easy on the vacuum system--just disconnect the vac line from the actuator, and they default open. On the newer versions, I think I remember disconnecting the IMRC harness and manually forcing the linkage open with a screwdriver.

sounds good to me. How about next weekend, that will give us all time to get all the parts needed. Besides this weekend is dedicated to getting my exhaust manifolds on.

I did similar on my 300ZX a few years ago. I was told to do almost the exact same procedue (vacuuum line in the bottle of cleaner), but to actually let it stall and leave it for a few minutes. That wat, there will be lots of the cleaner eating into the goonk that is all around the intake. Oh, yeah, the odd-coloured smoke that was coming out of the exhaust was priceless as well. Made it look like I was conducting mad experiments and something went wrong. And it didn't just dissipate, it went down the streey in a sort of brownish-greyish cloud. But the car ran much better after that

Oh yeah, has anyone tried the Carbon Clean Motor Vac service? I think that it does essentially the same thing. www.motorvac.com

Yeah, I did that with my old Miata, didn't seem to do much good though. Perhaps it just didn't need cleaning.
Going to try it on my SVT one of these days. 127k miles, never been cleaned. I bet it's really yummy in there...
