Hello, I have the car listed above SL model. As I’m changing the spark plugs, I noticed a little hose/tube broke off and I’m wondering what is it? Can I drive with this broken? It’s connected to something on the side of the intake manifold.

That part is used for the active intake runner controls. It is best to replace the part even though the engine will run it is not optimal. I have included how to change it out in the images below. Please let us know if you need anything else to get the problem fixed.

Hello Ken, thank you for answering my question. Last night I changed my spark plugs because I had a p0303 misfire code and I’ve scanned twice after changing the spark plugs, yet the code is still there. Now my car won’t accelerate past 20 and check engine light keeps flashing if I try to go over 20 mph. Can you please help me with what it can be? I’m so frustrated right now.

Also, I can’t seem to find the part I need to replace it, the hose snapped off, so I think I have to replace the hose and what it’s connected too. I don’t know what exactly to search up when buying the part. :(

Here is a picture of what it broke off of, I tried to search up the numbers that are on this part. However, I still can’t find it anywhere.

This part is dealer only, you must call the parts department for a replacement.
