GP's Silver Sleeper

[GreenPanther]

Well after only having my car for about a week, the mods have started.
This is a 2005 ZX4 with 74k miles.

I originally wanted to keep the car mostly stock and avoid adding anything that would draw attention on the road. I don't want to be pulled over more often simply because of a car's looks.

Then I checked my fuel mileage after the first tank of gas.......17.4 MPG. I was pretty disappointed as I hoped to get better mileage than the Jeep I traded off for this.



This is where my quest for better fuel economy started on Friday.
So far since yesterday:

-New Autolite 104 plugs gapped at .055
-Removed factory air intake and made my own SRI
-Installed FSWERKS 2.5 stealth exhaust





Here she is last week.

On my quest to hunt down anything that could rob fuel economy I also found I need to replace front driver side wheel bearing. Then after looking for the PCV valve, I could see the hose attached to it is split. So those are on my short list of things to accomplish in the near future.

Then re-check the MPG to see any gains. The added peppiness is not bad either.

You have a Duratec, I don't know much about that engine, but a good tune up will help. IIRC, you have a lifetime air-filter, maybe you should clean that. Also check the fuel filter, spark plugs and coil packs. Depending on how you drive can also lessen or greaten fuel economy.

Your engine takes really well to bolt-on mods, so a lil aftermarket support and you will have a real fuel saver(as long as you stay off the gas lol)

Happy modding!

Also keep in mind winter fuel nets u slight difference in Mpgs..

But beside that you should be getting much better fuel economy..

Like previously stated, clean ur filter, and tune up and do a test again.

I think I have a good start so far. Plugs are changed, new air filter set-up, new exhaust.
I should see some improvement this week. I know the mileage seemed abnormally low...even for winter fuel.

Glad to see you have a good sense of humor about your situation!

Would you just use something in an aerosol can, anything in particular you would recommend?

The maf is expensive so something like this^^ should help it. The o2 sensor is around $40 so replacing it would be an option. Cleaning the o2 I haven't tried and all the ways I've herd of (like soaking in gasoline) seem not proper.

Well, I am making some progress with the car and improving things. After replacing the factory air filter with a sri and installing the fswerks exhaust, the car came to life a little. Last tank I was up to 20mpg. This tank I have gone only 120 miles since full and it has used over half a tank of gas.


I noticed a crack in the pcv hose and a good bit of greasy crap in the throttle body. I was quoted $90 to have the pcv replaced at the local dealer.

After the tech looked at it, he came back with a quote of. $482 plus tax. --- I ended up leaving until I can find a more cost effective way to replace it. I was pretty dissapointed.
