What is your question?
pcv valve is stuck trying to replace but the grommet as well is tough as hell cant get it out do u think using those clamp pliers would work i ordered some for a friend to drop off in a little bit im here at work rn. also how do i fix the P0171 and 174 code im replacing the pcv cause i heard hissing near it which seems like it was that because it does move when you moved it side to side. also will replacing the safety switch fix 1780 it said park neutral switch mafunction and transmission solenoid switch circuit.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like your GS300’s PCV valve is putting up a fight! If that grommet’s stubborn, clamp pliers can definitely help grip it, but be gentle—old rubber can crumble and leave bits behind. A little spray of penetrating oil might soften it up just enough to wiggle free. For the P0171 and P0174 codes, you're on the right track since they usually point to a vacuum leak, and that hissing near the PCV valve is a big clue. Replacing the valve and checking for any other loose or cracked hoses around the intake should help clear those codes. As for P1780, if it’s pointing to a park/neutral switch malfunction, replacing the safety switch could indeed fix it. It’s usually a straightforward job, but make sure the wiring and connections are in good shape too.
