Spring Tune up

[sonicx]

*Never too soo to be starting something like this*

Future Needs:

Spark Plugs (anyone know what I should go with)?

Front 02 sensors (anyone know of somewhere cheap)?

New Battery (brands)?

Anything else should I do for a tune up? Got the tranny fluided & fuel filter changed about 10K ago.

stock plugs, since you dont really have any mods, make sure you put some dielectric on the bottoms of the boots before you reinstall them. do you really need front O2's? bosch ones are good. stock battery-you get what you pay for... supercharger bolt on.....?

My gas mileage is starting to suck really bad in the last several weeks. Late summer/Fall time I was getting tad over 300miles for a tank of gas. Now I am at 230ish. I've read on forums that your front 02's go "lazy" my car is just 200miles short of 70K.

cold weather and winter blend gas make for shitty mileage. at 70k miles your O2's are probably ok, but you can replace them if youd like.

cold weather makes your gas mileage worse. 2002 galant gets 325-330 miles per tank in summer but right now i am getting 270 or so.

A good thing to get is a MAF cleaner/electric cleaner to clean off your Mass Air Flow sensor.

I have some said electrical cleaner...

Agree with other posts. Your 02 sensors are probably fine, you don't see them go bad under 100k just check the connections. For plugs go with Ford spark plugs. JJ has a great point definitely check to see if your MAF sensor is clean. A clean MAF sensor is something that is easy to overlook.

a dirty maf sensor usually makes the engine think its running rich and will lean it out, which would increase mileage. i would leave the maf alone unless you had a filtration problem..... by cleaning its possible to do more harm than good.

Thanks Guys, I'll try spark plugs this springtime. Especially if said 02s are typically ok & I've cleaned MAF late last summer.

Just watch your MPG once it is 50+ for a full tank and see if it get back up there.

I look at plugs, wires, pcv valve,new fuel filter, cap and rotor(only 95 and older mustangs have). almost ever spring.


also clean your battery terminals at least once a year and check to make sure your ground and positive wires have good connections.
