I asked about the second sensor on the intake and he wasn't sure about it. The two in the first picture, the one on the right is my IMAP? I'll find out when I pick it up but I'd like to order the other one.

On the second photo, what's the larger pipe going straight down? I believe the other one is to the AC compressor.

Third pic, their are two lines going over to the exhaust pressure sensor. Take both off to clean or just the one steel one?

I finished watching the tune up videos today at a job sight, but it's all focused on the CM871. Mine being a CM870 its on the other side/looks different. Heading in now to look for carb cleaner. Looking forward to tearing into this when I have time.

Thanks, all.

There is no IMAP (Intake Manifold Air Pressure and temperature sensor) for the CM870. Instead there are the intake pressure sensor and intake temp sensors separately. Here is a pic ...

   

And the exhaust back-pressure sensor...
   

and the "Magic Plug" located right next to the fuel filter on the intake side that shuts down/closes the EGR when unplugged...
   

And the Delta-P sensor hidden behind everything next to the electric fuel pump. it has 2 tubes that feed it that like to clog up too.
