I just got back from the dealer and they told me I need Spark plugs and wires, an o2 sensor and a maf sensor, they wanted to charge me $750 for it, so I was wondering if I can do it myself and also how can I test the MAF sensor, what resistance should it read if good?

any help or writeups would be awesome, thanks ahead of time

Is your "Check Engine" light on?

You usually don't just recommend 02's and MAF's for service. Whats going on with the vehicle?

well the dealer took care of it for $600, but my car is approaching 125k miles, is there any Preventative maintanance I should start looking into?

Normally if the car is running OK and the check engine light is off, there is not a problem. Not saying these wasn’t a problem with the engine but the MAF and O2 sensors are not normally replaced on a preventive maintenance schedule.

Recommended timing belt change is 90K miles. If an automatic trans and original fluid change it plus differential fluid.

are there any diy's where I can learn to do alot of these PM sort of things?

Asilva,

Most of the pm items you can do by yourself with a service manual and a few basic tools.

I am reaching 200k miles on my rig. In the last 100k miles, its only been in a shop twice. Once for new tires, and once to get the timing belt/water pump/belts replaced (it was winter, and i didnt feel like doing the work in the freezing cold).

I am sure this forum and others can help you with various projects. Just do a quick search.

good luck
