I bought my car and there was nothing wrong with it. Now everything is starting to catch up with me. I need a crankshaft position sensor, and O2 sensor,and rack and pinion. Anyone know the price range i need to look at? (200-300)?

O2: $70
CKPS: Not sure, $40 seems like a good target. Might be more or less.
Rack and Pinion: $180~

You can look on autoparts websites and find actual prices, but those will put you in a general range. Labor is going to kill you on the rack and pinion, unless you're doing it.
