I have a general idea of what those hoses are for but what sort of problems would something like that cause. I am going to replace it asap.

Thx
It's just a PCV hose...which has nothing to do with starting unless your PCV valve is bad. I agree with your plan to check the plugs, and fuel filter. The coil packs I'd only check if your Supra has more than 100K miles. Also add checking the air filter to your list, and run some fuel injector cleaner too (if you haven't recently).

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
