Hey Guys and Gals,
Well, we're now officially part of the Monty Club! I flew down to Vegas last week and made my way up to beautiful St. George, UT to pick up a familiar '03 Monty, ImNoSaint's very well outfitted rig!
I drove back up to Seattle and am really impressed with handling, mileage (previous truck was an 80-Series Land Cruiser, so this is a huge improvement...) and comfort! I spent my weekend replacing front brakes as they were getting pretty tired but had to get it to a shop to diagnose an emissions issue as we failed the smog test. Initially suspected a faulty oxygen sensor, but this is what the shop had to say about it:
"Failed emissions due to lean bank one and bank two codes (P0171 and P0174). Scanned computer, found long term fuel trim stuck at 12.5%. Found vacuum leak at intake manifold plenum valve assembly, recommend replacing this part to correct lean condition"
Unfortunately, this is a $900 part according to the tech, another $500 labor to get it replaced.. Before I commit that kind of investment, I figured I'd ask here first to see if anyone has had any experience with intake vacuum leaks, troubleshooting, etc.? I am considering driving it through the winter as is (no driveability issues, MPG's may be up a bit but not too worried about that), and when it comes time to do timing belt/water pump in the spring just rip into the intake as well and see if I can find an issue or leaking gasket to cause this issue. There is an exhaust gasket leak as well by the way, don't think that contributes to lean running though?
Anyway, hope someone may have some input. Otherwise, happy to be part of the club and big shout-out to Eric for holding the car for me and for a smooth transaction, cheers!
