  • bad gas or what???

    well i went to race trac 1 day got bout a 1/4 tank to make it till friday and the next day b4 i got more gas i was trying to get on the freeway and then all the sudden the car acts like its running out of gas the car was sputtering and missing VERY bad and so later i got more gas at shell filled the car up and every now and then it still does it,its been doing this ever since last friday and i dont know if theres bad gas left in my tank or is somthing else wrong with the car cuz i changed the fuel filter added gas additives and cleaners and got more gas and still does this at least 1 time every time i go off somewhere, can someone tell me what to do?? this is my 96 3.8 im talking about just to let u guys know...

    could be your tps try to see if your getting into the gas the same amount every time it does it tthen when it does it try pushing the pedel farther

      is tps throttle position sensor? i should mention it only does this when i mash the gas wether its alot or a lil bit, and sometimes when i start it it stalls

        tps = throttle positioning sensor thats probably not it if it stalls when you start it though

            i keep coming back to your map sensor since it only happens in low vac situations try putting in first and drive it up to around 3000rpm then nail it see if it does it then if not my bet is the map it would be odd though

                change the fuel filter again... it may have clogged with bad gas and then the new has build up since there was more bad gas in it.... otherwise i'm not sure. My dad's truck did this and we changed the fuel filter twice... it got better but still does it no matter what.

                  leave it in first so you can monitor rpm
