Just changed my spark plugs, PCV valve and Fuel filter and my car is running smoother and its more responsive. My brother got a full tune up done with nissan at 94k miles. Well guess what.. they didnt do jack s h i t. My fuel filter was shot, there was fuel dripping out not running freely. Can't wait to change my fuel pressure regulator. Just beware of what nissan does.. They only did my plugs and nothing else..

 

Score 1 for the diy-ers out there.


That's the first rule...never take it to a dealer. Especially not with reference like Maxima.org around.

 

You could have saved yourself the $10 and just rerouted the PCV so it wasn't spitting into the IM. Good job though. Plugs are definitely a DIY job.

 

Well it took me a good 30 min or so to do the whole job. I think the hardest part was getting the fuel filter out. that took me about 15 min of my time to work at.. I guess the best is saved for last lol.
