Does anyone have a list of the vacuum lines or a diagram that shows all of them. I have replaced
1) Brake Booster Line
2) MAP Sensor Line
3) PVC Line
4) Fuel Pressure Regulator Line
5) Fuel Breather line

What lines am I missing? Thanks!

 

How about check the PCV? [just kidding - couldn't resist ]

 

There are a couple more on the BPV/Throttle body that you could check. Also check the gasket that goes between the BPV and the intercooler horn. Mine was completely flat and I would have missed it had I not taken the BPV off the horn.

 

I am a country boy with dyslexia sorry

 

I am still hoping someone has a vacuum line diagram for my '05 MCS

 

Are you chasing a vacuum leak?

 

Check out www.realoem.com for illustrations of the vacuum lines.

 

I have been chasing a P1498 code for months I have tried everything except replacing all the vacuum lines.

 

Have you had it smoked or gone in there with some starting fluid to find the leak? Rather than just throwing parts at it.

 

I have sprayed starter fluid on almost the entire engine in hopes of some of the stuff getting in a crack or leak while motor is running. I am so tired of get less gas mileage and having the code light up my dash. I hate this code

 

I understand, I chased one for a while too.
