So first let me set this up for you. I drive an 89 Auto 325i(soon to be manual). I was in traffic for about an hour today, i had just gotten out of traffic and was switching lanes etc and going to accelerate from about 50mph to 65 or so to get to normal highway speed, but when i pressed the gas pedal nothing happened at all. Engine didnt rev, nothing. But it continued to idle/run fine with no hiccups, sputters, etc. So i changed lanes and exited since i would soon use up my coasting speed and be stranded.
When i was coasting down the exit ramp i found a sweet spot, where by barely (and i mean barely) pressing the gas pedal i would get some acceleration(again with no sputtering). After a few moments of coasting on the feeder i was able to accelerate normally throughout the range of the pedal and made it to a gas station. I noticed the gas light had come on, so i thought maybe i ran the tank almost dry. It filled up to its normal 12.9 gallons, so i didnt run it any lower than i normally do.
here are some figures of my latest MPG/ fillups that i could find in my glovebox(i know these figures can sometimes help with troubleshooting), and relavent work.
date trip odometer amount filled up mpg
7/7/2012 302 12.9g 23.4
8/3/2012 320 12.9g 24.7
9/1/2012 295.5 14.25g 20.7
9/21/2012 262 14.3g 18.3
10/4/2012 209.9 12.9g 16.18
I fill up almost as soon as the gas light comes on, but the guage usually has is in the red for a little bit before the gas light comes on. I base my mpg calculations on how much i put in the tank, since technically that should be the amount i used. I write it on the receipts after i fill up so i can try and keep track of any problems. As you can see this time, i only got 209 miles before the gas light came on, which is a bit less than normal. There are a few receipts missing, but i typically have been getting 260ish miles to a tank lately with around 17ish mpg.
I replaced the fuel filter on 3/4/2012 and it has about 2000 miles on it. Im pretty sure(tested it with multimeter) that my TPS is bad, and also my gas tank has a decent but not huge bend in the bottom of it, which i know could decrease the volume of the tank.
So with the information i have provided, here are my questions:
Any reason why my typical fill up is almost always 12.9 gallons before the pump stops?(like could there be something that only is allowing that much in)
Any reason for the almost complete loss of power today?
I do have spark plugs, cap and rotor, and oxygen sensor sitting in the garage ready to be installed as well. But all the parts on the car currently(other than oxygen sensor, pretty sure thats bad) seem to be working correctly to my knowledge other than just being worn/tired.
