Question about 1998 Honda Civic Coupe
My story: I bought this car a little over a week ago with no inspection and no indicator lights on. When I got it I took it right to get it inspected and found out I had to get the muffler fixed , which I did, then I went back and the sensors were reading not ready on o2, catalyst and evap. He tells me to drive it between 50 & 100 miles. I do and take it back and he checks the sensors and still not ready. So he says, "Let me reset your computer system, sometimes they might freeze up", but of course I have to drive it between 50 & 100 miles again, which I do and then I take it back and still not ready. So I take it to a shop to get a diagnostic test done. When I get there and tell them my story, he tells me that there's no point in doing the diagnostic because it won't tell us anything. He then tells me that I need to do a proper drive cycle. His mechanics can't seem to find one for my particular car so they say that there isn't one and I just need to drive it. So I do and then I go back and still not ready. Then he calls someone and they say I need to have a scanner put on it, which I do and the scanner doesn't show any computer issues or anything out of the ordinary, but this mechanic seems to have found the actual drive cycle that goes to my car. Yay, right? Wrong. Where am I suppose to be able to do this drive cycle in the Dallas area without interruption? Is there any other way to fix this issue besides the drive cycle or does anyone know of a place in the Dallas area I could do this drive cycle cause I really feel like banging my head up against a wall right about now. Please help.

In most state,it requires 5 out of 8 ready-ness data fill up on the computer momory.
The entire memory will CLEAR when you try to clear the MAF code.
You need to fix the MAF sensor first.
The inexpensive fix is to clean the MAF sensor with CRC MAF cleaner or electronic part clearer from Radio Shack.
Do not forget to clean the contacts too.
The correct fix is to replace the MAF.
Make sure the check engine light does not come back.
To fill the REQUIRED data into the computer you have to complete few drive cycles.
To keep this post short,just drive the car for 2+ days (10 miles min.) with mix highway and local driving.
If you want to be safe drive it for 4+ days (20 miles min.) before return to smog test station.
Drive more will help fill up the required data fields from the smog station.
DO NOT reset the computer.
IT WILL CLEAR the stored data!
Please post more information on the comment window. I will follow up on it later.

As a rule it takes about 50 miles for the computer to finish it's readiness tests. Some take longer so I would drive it about 75 miles and then check.
