So, the time is coming closer for me to sell my tC. After being hit by a semi, I figured it was time to fix it up and let it go. The biggest thing I have to fix is actually a small thing. My check engine light came on well over 10k miles ago, and I had it immediately checked out. The code it was pulling was for a large vacuum leak. I was informed that it would idle a little on the rough side and not get excellent gas mileage, but the car would still function with no engine problems, which it has. I have been looking for the past 10k miles for any info on how to replace the hoses such as: how much do I need, what size do I need, how to pinpoint the leak to ensure it's actually from a hose, etc. I have only been able to find kits that say to include everything, but I'm not looking to spend $50 plus on some hoses that I know are only a few dollars. So, if any one can point me in the right direction, or can inform me on how to do this, it would be greatly appreciated.

 

you could get a smoke test to find out exactly where the leak is. and i believe the sizing of the vacuum hoses are on the hoses themselves

 

Thanks for the heads up on the sizes being on the hose. Tried finding a leak the other day, and couldn't find one. So, did a little bit more research, and realized I have never cleaned my MAF sensor. Turns out, I have been driving on a dirty one pulling a check engine light for over 10k miles. Over thinking FTL.
