However, this morning, with like 35 degrees, it started just fine and stayed on. On my way to work and back, it didn't cut off for a split second like it used to, and I started the engine a few times during the day just to test it, and each time it started right away and stayed on.
Still, I bought the Chilton manual, spark plugs, PCV valve and fuel filter and I intend to change all of them this weekend. I bought Bosch 2 Platinum spark plugs, which were like twice the price of the regular platinum ones. Are they really good? Anybody tried them? I couldn't buy new cables because the whole set would be $45, and I'm short on money. Is it really important to change the cables too?
As for the PCV valve and fuel filter, I purchased those at Car Quest, and they're their own brand. Should I try to get the AC-Delco originals, or are the Car Quest products good quality?
Thanks for any advice,
Sebastian

Personally, I would stick with a/c delco. I don't know what it is, but my PA had always performed better with factory brand plugs. Everyone I've talked to has recommended using a/c delco on GM vehicles (unless they are otherwise modified, of course) As long as the PCV valve and fuel filter are the right ones for your car, they should work fine. I've used throttle body cleaner to clean both the throttle body and inside PCV lines
(as directed on the can) and the car ran GREAT after that! It cleans out unseen sludge and really improves engine power and idle quality.
And as for your wires, that really depends on how old they are. On most cases I've seen, they usually are ok to be reused. However, if they are really, really old you should change them with your plugs (kill 2 birds with 1 stone, you know?) Good look with the tune -up!
