Yea, the O2 sensors are installed to the TPs. Hmm... this is turning into some really good discussion.
I'm going to change and examine the spark plugs while doing some maintenance work. Then I'll get the leak test done and fix any potential leaks. After all is said and done (and hopefully the car still runs), I'll try to see if I can peek at the exhaust manifolds on the next oil change. I'll keep you guys posted in a month or so.

Although I can go for something simpler and cheaper, I'm just holding out for something I hope is more useful and permanent. Tuners, please chime in on what you prefer to have handy:
