    Question engine problems

    well this issue took away my complete weekend and It still there. The symptoms are, when I give the car gas it sttuders, shakes, and the rpms go way too high. But it only does this when im trying to pick up some speed, if I give it gas in a normal way nothing happens. The car has 79k miles, has never done this before and I have not done anything different to the car. I changed the spark plugs and it is still the same. Im thinking maybe some bad gasoline? Help please

    no codes? before you waste a bunch of money throwing random parts at it, do some testing, maybe check fuel pressure, or hell, just pay $90 for a shop to figure it out.

    Sounds like a possible vacuum leak? Is it auto or 5 speed?
