Power lag after carwash

[coolbreeze551]

I am experiencing slow throttle response and what seems like a decrease in power after my car is washed. I don't wash the engine before I experience this and he only water that might be effecting it is the "under wash" when you drive into the car wash and some hoses automatically spray underneath your car. Is there something located down there that would be effected by short spray of water (about 1 second long or less)? Has anyone else experienced that?

This can be dangerous... there have been reported cases of engines which have grenaded by hydrolocking after running through an automatic, or hi-pressure car wash. Seems the water floods the intake after shooting into the side intake vent.

Rare, but it has happened.

I think most people hand wash.

Cheers!

Why do you take your car to an auto wash??? It should only be hand washed.

The Spark Plugs might have gotten some water in them.

They are located behind the left side rear tire.

I would never run my Boxster through a car wash...it's not wise at all. :ah:

Actually, it's a 6-cyl. Boxer engine - you have a bank of 3 cylinders (and 3 plugs) on either side of the car.

Given that it's coil-on-plug, it's unlikely that water can get in the plug tubes.

Cheers!

I can't imagine that there is anything exposed underneath the car. But, even so, I wouldn' t be putting my convertible through a high-pressure anything. It is so small hand washing takes only a few minutes.

There may not be much exposed under the car, but you have a pretty gaping hole on either side rear quarter panel - the engine bay cooling fan exhaust on the P-side, and the engine air intake on the D-side (which leads straight to the engine intake).

Sorry, I guess my original post was unclear. I don't run my car through an auto wash. I hand wash it, however, when I drive into the washing bay there is an option for an under-car spray of water to get spots under the car that you normally can't with hand washing. I do not take my car to an automatic car wash, I always hand wash, just the quick water spray underneath is automatic.

What happen if you drive in the rain and over a puddle of water?

[Keith Newby]

They're cars after all. Wash them how you see fit and don't apologize for the method you choose. Damn!

Washing Bay?

Are you using a high pressure, coin operated wand on the car?

Have you taken the snorkle off the car?

If you got water into the drivers side air intake, the air filter could have gotten wet/damp. Check the air filter and air box to make sure there is no water inside.
