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?
