Hey guys sorry to bother you with this. I just changed my spark plugs on an 08 Is250 two days ago and it went without any problems. After I did that I started noticing a sort of grinding noise or some weird water pressure noise. Sort of like when your shower head is clogged and struggling to get water out. It's hard to explain.

The noise only occurs randomly when I accelerate after being stopped at a light or somewhere for a little over 45 seconds. The sound usually only lasts 2 seconds at most but it's so random that I can't predict when it's going to happen. I'm not sure if it's related to the spark plug change and me not hooking everything up properly but I can swear I triple checked everything. My acceleration and idle is normal so I'm just lost as to what it is.

It almost sounds like my brakes are sticking on my driver side and I'm just being paranoid because of the spark plug change.

Any ideas would be great and helpful. Again sorry if it's a simple fix.

 

Hopefully it is just a bracket or something wasn't fully torqued or something is loose and rattling around. It does not sound like you installed something incorrectly, because the care seems to be running fine.

GL!

 

Thanks for the reply

Hopefully it's nothing serious. I triple checked everything while I was putting everything together so it can't be anything to do with the spark plug change. It's starting to do it as I reverse out of the garage as well. I'll have to investigate some more this weekend.

I was just hoping someone here would have some sort of idea of what it could be.

 

Hi did you figure it out? I have the same issue. Thanks

 

Last post was 5 years ago. I wouldn't hold your breath...

Tell us more....

 

I wish I had an answer for you man but shortly after I posted the noise went away completely. I couldn't replicate it even if I tried.
