With the fluctuating gas prices, I am just curious.. Will BRAND NEW spark plugs and 8.5mm wires improve my gas mileage on my 90's 3.1? Im thinkin it will.. I will tell ya this.. The son of a bitch has more pep than ever.. Holy balls, I was at 90 before I knew it! I only looked at the speed because the front bumper started to shake as its on there by I believe 2 bolts now.. lol.. Anyone who knows, let me know!

Where do I find the O2 sensor at? And this top engine cleaner dealy you speak of? lol.. Great gas mileage kicks ass.. I spose I can save some by NOT flying down 35E at 90..

No advance autos around me.. M dad can prolly get it dirt too.. Where is it located on my car? Somewhere in the exhaust line? Or more in the engine area of things?

Not unless you want to drive all the way out to Elk River, as there's one that just opened up out there :D ...

 

Oh yeah, and changing the plugs, wires, and O2 sensor really does make a small improvement in your gas mileage, fo shizzle! I replaced the plugs in my Regal this past spring (bought the car in December) and the center electrodes were worn all the way down to the porcelain! Well, instead of going 300 miles on a tank of gas (something like 21 mpg) on the old plugs, I can get 330-340 miles out of a tankful after the tuneup (close to 24 mpg.) So tuneups are not overrated!

My dad's shop.. I got them his cost, so no mark up.. I like them.. They seem worth it.. Only a little more thaqn standard 7 mms.. This brand is like Mag xts or something.. Noit HIGH quality, but not shit either.. Theyre nice.. All I ran on my 6k..
