Engine tune up and 02sensor

tune up and 02sensor

2002 prizm
Hi I need a tune up and my 02 sensor(s) replaced. What should I do to spend as less as possible? Can I do a tune up myself? and or the sensors. I haven't done either of them before. I was thinking about doing my own spark plugs and possibly my sensors and let my mechanic do the rest of the tune up so that i gotta pay less. also with the sensors my mechanic said I'll have to take the passenger seat out and others tell me it's real easy. do i need to use a special wrench?

No it is easy. All you need to take the 1st sensor off is a 12mm socket and the other one probably just a standard wrench. I am not sure that you have to take the seat out. You might be able to just reach under it. The spark plugs are easy to do if you have the spark plug socket that grabs on to them so you dont have to try and reach into the hole to get them out. You can buy one at any auto place if you don't have one.

sounds good to me
