Okay, me and my buddy were talking at work, and he said that he checked his Hyundai Elantras Cel Codes, and found some problems. And im not gonna lie, that was the first time I had ever heard of Cel Codes. So im slightly intrigued by this, and i was wondering how you check it. I know its something under the dash but i have no clue as to what. Some help maybe? I was hoping checking that will lead me to why im only getting between 200 and 220 miles on a tank of gas. Because it really should be more. Or maybe im wrong about that too? Idk. Help? lol.

CEL codes are checked in different ways depending on what year your car is. First, you know your car is running any codes because the Check Engine Light (CEL) will be glowing on your gauge cluster. If it is not glowing, then don't even bother checking it. Since you profile says yours is a 1993, it is an OBD-1 car. This means the CEL is checked by completing the circuit of 2 wires under the dash, generally with something as simple as a paperclip or speaker wire more preferably. If you had an OBD-II car, then you would check it with a scanner that you plug in under the dash.

As for your poor gas mileage, its 1 of 2 things that's most likely causing it for you. 1, your foot is pushing to hard on the gas pedal or 2, you need to perform some simple maintainance on your car like a new intake filter, oil change, tire pressure checked, etc.

Hope this helps

well the car has a CAI with a brand new filter, so i doubt thats it. but ill check my tire pressure, and get an oil change, (cuz im due for one anyways) and hopefully that might help.
And btw, my foot is only pushing too hard on the gas pedal when im late, or at the track, and thats not often. lol

I was only getting 250ish outta a tank in my del sol S, I drained and refilled my tranny fluuid a fe wtimes to get the old shit out (tranny WAS slipping, now butter smooth), seafoamed my car, plugs, wires, cap and rotor, NEW THERMOSTAT. people sometimes dont realize how much gas you waste when your car isnt at operating temp.

Proper tire pressure, and get your O2 sensor testing. Im now getting 320-370 per tank easy, with some hard accelerations on the interstate

Let us know if you got any more questions bro

about how much did all that cost you? im just looking for a ball park...i know a lot can be done myself, but some shit i wouldnt wanna mess with ya know? i think im goin tomorrow to get my oil change cuz i need one, and my buddy works at lube stop...cheap as shit.

 

[frathouse87]

Well be careful with seafoaming, oil change is a good idea, and just make sure everything works right.

tranny fluid is 5-8 per quart, 2 per fillup, figure 2 fill ups should be fine, so maybe most 35 bucks?

plugs and wires, 40 bucks, NGK ONLY :btu, thermostat was 12 bucks, cap and rotor 10-20 depending on brand.

seafoam is about 6 bucks a can, get the one liter can, 1/3 in oil, 1/3 in gas, and 1/3 sucked through the vacuum line that attaches to your brake booster.

 

[mattliston]

seafoam in oil DEMANDS an oil change within 250miles, but drive at least 100 miles, to clean the system

runrite makes one of these. they work real well, they sell them at jiffy lubes. 60 bucks for the service. (i work at one, had it done to my car)

 

[mattliston]
