What year and model is your Mazda? This sounds electrical and will probably be one component such as a bad MAF(mass air flow sensor). This would cause all those symptoms. I would like to verify the the system set up first though so I can be more sure.

I have a 2002 buick lesabre gas smell inside the car they said its the map sensor


Ok, Is there a question?
Usually with gas smell, I look for external gas leak? If I find nothing, I check the evap system. Next, I check if the vehicle is running rich or lean? Were there any applicable trouble codes? If so, what were the codes? The map sensor could have a problem?

Car runs fine at times then will not start. Sprayed carb cleaner in air filter and then it starts but dies when i start. The next day car starts and runs fine.


It sounds like your car isn't getting the proper amount of gas. You say your mechanic changed the fuel pump and the regulator. Id have him run a diagnostic tool on it to see if it throws any other codes. Its getting fire. Try changing the FUEL FILTER. it maybe clogged. maybe the pressure regulator is not giving it enough pressure to push the gas into the engine or maybe the fuel pump is only working at times. Does it run good and then start to spit and spudder then die? if so its not getting gas some how. Idk if you can adjust the pressure regulator or not. i mostly work on old school cars.

Code F48 is for low freon in the ac, and code F49 is for the computer turning off the ac compressor because the pressure is too high or the engine temp is too high. So neither code would have a direct effect on the engine running.
You may have to get a mechanic involved that can watch the data stream coming into the computer and check the exhaust gas to see if it is too rich or too lean.

1999 honda accord seems like it isn't gettign a steady fuel supply, it keeps sputtering and almost dies but when I pump the gas pedal it revs back up. I just put a new O2 sensor in and it sounds l


First question is - is the check engine light on ?
If yes you should check it for codes next.
You may have to use a scanner to watch the O2 sensor to figure out if it is too lean or too rich. I would also check fuel pressure at the rail with a gauge to make sure pressure is normal. Could be a faulty fuel pressure regulator among other things.

Poor acceleration and low gas mileage,smells rich at idle


You are off to a good start, MAF when it is contaminated it leans the vehicle out it doesnt make the car run rich, depending on the fuel strategy of the year make and model,and of course the engine size make all the difference,bad ignition coil make a car run rich shorted 02 sensor that lean bias make the car run rich, worn timing belt ****** timing and causes the car to run rich.so lets hear the results

I have a 1990 Mercury Marquis, the fuel is running really rich. The car will only idle for a minute, then dies. It will run if you keep your foot on the gas, as soon as you let off the gas, it cuts out and...


there are two things you need to check out 1. is the check engine light on... if so its most likely an oxygen sensor that has gone bad, the oxygen sensor tells the vehicle the air/fuel ratio to use to make the vehicle efficient on fuel.. thus if its bad the vehicle will either run extremely rich, or way too lean.. and the secont thing to check out is your fuel pressure regulator, if its stuck it will allow the fuel to flow endlessly...hope this helps

1989 corvette runs rough surges between 600 and 700 rpm. drive it for 20 minutes it totally runs awful. had to have it towed the other day..waited two hour for flatbed started car and it ran again..code 44...


try replacing the fuel regulator,that would make it get too much fuel and the code for o2 sensor will come on saying too lean or too rich fuel mixture,and it would run rough

How do i adjust the rich/lean fuel mixture cracked intake


You can't do it with out a tech 2 scanner, so your going to have to go back to the Mechanic to have it reprogrammed. As long as it's running rich, your going to have bad fuel economy and will not pass the emission test when you have to have it done. Good luck and glad to know you got your car running almost 100%

Hi, I get code number 51. Not sure what I can do to find and fix problem. Thanks


Code 51 is Wide Open Throttle Problem. You need to replace your fuel filter, possibly drain fuel tank and clean fuel pump pre-filter. That is in the fuel tank. If you have the cash, I would replace fuel pump while inside the tank.
