Was 37mpg, now 23mpg?!

Is it sending you any codes?

[Spike]

Yes, the Check Engine light comes on, but only for a minute or so and goes back off. I don't have a code-reader, and Advance/other stores only check 1996+ automobiles.

Alrighty.

The new Oxygen Sensor is in! The car feels much better, and doesn't sound so much like a diesel truck anymore. Helped a lot with my high idle, too (without touching the peddle, I was going 0-15+ very quickly just letting off the brake).

Unsure if it's fixed my mileage yet, but I'll be making a 200-ish mile round trip tomorrow (going to a funeral, 4 deaths inside of 3 weeks, 2 of them within 2 days), so we'll answer that question.

Thanks for all the help as of yet, and I'll be reporting in with my mileage as soon I can.

You don't need a code reader. Above the brake booster there are about 4 plugs that appear unused. There is a black plug with a single wire going to it. I used a piece of wire and cramped a spade terminal on one end and a fork terminal on the.other. spade goes into plug, fork wedged into a grounding spot
Turn the key to the on position (not cranking the engine). The check engine light will start flashing the codes. I think 15 is rich and 17 is lean. My light is on occasionally, mileage used to be mid 40's, now 37.5. I'm getting a 17 code and it smells rich.

You'll need to disconnect the battery to clear the codes I believe. Usually 10 minutes works but I like to leave it overnight.

Whooohooo.

Seems the Oxygen Sensor fixed my problem.

Averaged around 35MPG on our trip yesterday.

Although the Check Engine light still comes on when I idle for a minute or two.

Is this checking with an Ohm meter? Wasn't sure exactly what you meant I needed to use.

have your injectors cleaned and seafoam the intake.

[Larry Hampton]

I ran seafoam in the gas a few tanks ago.

Are you talking hooking up a vacuum line.to the can?

Cleaning injectors, pull them out and soak? Or can you get a can of cleaner that you disconnect the fuel line and run it off the can?

[FestYboy]

yes, yes and/or yes. if you want to do the injectors yourself, borrow or rent/purchace a sonic cleaner and devise a way to hold the injector open via a 9v battery and then place in the cleaner with appropriate cleaning agent. just like Lanemeyer did with the HLAs

[Larry Hampton]

One of my old bosses had a early Lexus 4 cyl. coupe. He pulled his injectors out before a NFL game and poured fuel injector cleaner like you'd put in your tank into a rattle can lid and set the injectors in it. After the game, reinstalled and it ran like a new car.

Are Aspire injectors the same? Maybe pull a set from PAP and have them cleaned, then install them. Or swap and have mine cleaned and reinstall.

[TominMO]

Doesn't fuel system cleaner, poured into the gas tank, do the same job? That's what it's supposed to do. Sez it treats up to 20 gallons, so in a Festy tank it's double strength.

[FestYboy]

ahh, but sonic cleanig gets into the nooks and crannies that the treated fuel won't normaly reach.

[M3NTAL]

And fix your fuel level sending unit now ! lol

[getnpsi]

I use the injector cleaner on a quarter tank or less. Techron is the only one worth buying if you are going by the doses you are supposed to. I've soaked just the tips and a lot of gunk comes out into the solvent even on injectors with low miles. You can always add some e85 to your fuel and buy a backup fuel filter, that makes a lot of stuff come out. I'd actually do that then pull the injectors and do them after the stuff goes thru the tank.
