2000 Chevy Malibu. 180K miles.
the car loses power, stutters, rpm's go crazy, and just bogs down whenever I get on the high way and accelerate up an incline. One time I took gas cap off just to test pressure in gas tank and it got worse! Could it be fuel pump?
Actually...my intentions were not to test the fp taking the gas cap off. I actually forgot to put it back on one day and noticed a huge effect of what was already going on.
