First off I wanna say what's up y'all!?! I just recently bought my first ever Mazda last week and it ran great the first day I had it. Then on the 2nd day it ran great for the first 1/4 mile down my road to the stop sign and taking off from the stop it fell flat on it's face. So I tried pedaling it to get power back with no avail so I had to stomp on it because a car was coming up on me and once I hit 12 mph it lunged forward and instantly regained power. So I took it home and started researching when I found this wonderful site and here I am now.
Since then I've went on plenty of test rides to get a better feel for exactly how it was acting. There is no set path that this bogging follows, it does it on the highway at high speeds, it does it starting from a stop and it even rarely bogs down when it is idling. So I replaced the air intake snorkel because it was cracked pretty good and it ran great for about 15 minutes then bam I went to take off and she fell flat on her face. So my dad suggested the maf sensor and I replaced it instead of just cleaning it and it ran great for about 15 minutes again then same crap. Then I disconnected the maf sensor plug and started it and let it run for 30 seconds, shut it off and reconnected the maf sensor plug. I fired it up and it ran great for about a day then quickly the issue came back! I tried a few things like checking wire connections, resetting the ecm and checking grounds and during the middle of my test drives I needed gas so I filled it up. Once I filled the tank up completely it stopped having any issues whatsoever. I continued test driving it and it didn't bog or act up once until the gas gauge dropped down to 5/8ths of a tank. It started occuring slowly and as the fuel level dropped lower the symptoms continued to increase and get worse...
This leaves me to believe it's a fuel issue and I had read a thread when I first found this site that mentioned something about a fuel pulse sensor or something to that effect, not the fuel pressure regulator, fuel filter or fuel pump but something different. I've searched for the last 2 hours and can't find that thread again so if anyone could fill me in on what it's actual name is I'd greatly appreciate it!
Now on to my question, do y'all think I'm correct about it probably being an issue with the fuel system since the issues completely go away when the gas tank is full and if so where should I start exactly with testing? I have the 327 Bluetooth reader coming in the mail tomorrow, so until then I can't check the codes. Since I've had it the thing hasn't thrown a single code until tonight once it reached a quarter tank of gas and it basically fell flat on it's face 90% of the time I hit the throttle.
To my knowledge it has no modifications, it's 100% stock and it's a nonturbo 2.0l with an automatic transmission at 142,600 miles. I bought it from an elderly couple that used it for church and a grocery getter. They always had it serviced regularly and took great care of it.
I greatly appreciate any input, thanks erryone!
