    Got an '01 GTP, and I'm working a code for a bad MAF sensor. Whlie cleaning the sensor, I noticed a cracked vacuum hose to the left of the MAF sensor that is a molded elbow from the throttle body housing to a hard plastic vacuum line.

    It's a molded elbow that has a large size on the end that goes on the throttle body housing and smaller where it connects to the hard plastic line.

    Where can I get a find a look up screen for the part number, and find a source for the hose or materials to make it up?

    Thanks,
    'Manche

    Only a dealership will be able order in those complete hoses, not something a parts store will have.

    Otherwise most of us just buy vacuum hose from a parts store and run our own lines, they sell plastic T's aswell if you needed them.

    i got a fat vac line that fit the tb, then a smaller line and pushed it inside the fat hose, then pushed the hard line into thinner line.

    like so.

    Sounds good enuf.....about what I figured. Thanks for the suggestion.

    Gotta go back for the MAF sensor anyhow, so I'll get some. I cleaned it and cleared the code, but it still idles rough. I sealed the hose crack with goop so I could eliminate that for a short test.

    dont get a aftermarket maf, your car will hate it, as well as your wallet.

    get a junk yard maf, or a used one off e bay. most run like 40 bucks.

    I read the posts about aftermarket ones, but bit the bullet and put one on about an hour ago. I hung onto the receipt if it goes bad.

    Found a piece of soft vac hose that fit the smaller hard line and easily stretched over the larger T-Body nipple. Sensor was a Dorman that I got at Advance for $157 bucks...ouch. They tried to sell me a reman one for $118, but I wasn't feeling it.

    It smoothed out the idle instantly, and on the 5-6 mile ride home, the mileage went up from 22 to 24.5 mpg.
