Default my honda civic check engine light on again?

I have a 98 honda civic lx and it has the code that says" fuel too rich" ? it disappeared when i put gas on it, but it came back again after 2 days. when it disappeared, i took it to the mechanic shop just to see what it had and he said it "was nothing serious because the check engine light was off, but of course this code was in the system" , so he told me not to worry about it unless it turns back on again. It did this morning, i dont have more money to spend on this car anymore at least right now ( i've changed a total of $500 in replaced mechanical parts , distributor and ignition key) until my next pay check, the next week. So is this a serious problem? can it wait or what can i do to "fix it once I have the money. if there is a price how much could it be?

btw he said that was the only problem my car had, everything is fine its just that thing.

Please excuse my ignorance this is my first time owning a car and dont know much about it and i dont want to go to the mechanic shop and pay 60 dollars for a diagnosis .is

thank you

the code is P0172 "system too rich" bank 1

Some auto parts stores will do the engine check for you for free, and can sometimes give advice.

Call around.

My husband does this all the time.

It sounds like you might need a new fuel filter.

Call around to see if any local trade schools teach this stuff.

They're always looking for cars to work on, and you only have to pay for parts.

And AAA says they now have a diagnostic service on thier website, if you're a member.

It might be worth it to join AAA for $49 a year.

They have other benefits too.

Look at their site.

The front 02 sensor the MAF sensor and the engine coolant sensor for the computer all can cause a rich condition. You need a mechanic with a $2,500 scan tool, not a code reader, to check all the sensor and solenoid readings to make sure they are in spec. That's the only way to find the part that is causing your problem.

Stephanie ,, as long as your check engine light it on steady and not flashing your fine to drive the car providing it runs normally ,,, it sounds like the mechanic you're going to might not really have a good grasp on what is going on with your car and how to diagnosis it,, once you have money again I would suggest going to another good shop and really having the scan data looked at paying special attention to short term and long term fuel data, ect, and map and baro sensor data, the answer will be there,,, , (maybe ask friends what shop they go to ) ,, ( not a pep Boyz or tire store,,) sounds like a possible fuel injector( which would involve an injector balance test ) or valve adjustment issue,, sorry for your trouble ( rich condition in your car ) those cars are typically very problem free but it's getting old , best of luck!
