i have a 98 accord ex 4 cyl, two weeks ago i let my gas get really low and it was very cold that night, next time i started it up, my battery was dead, after jumping the battery, the car was running really ruff, once warmed up it idled fine, now no matter if im in park or if i have the car in gear, at 2500 rpms it just loses power and makes a noise as if im reving the gas, and if i put the pedal all the way down it acts like it just wants to die, but its at 2500 rpms every time, i've tried dry gas, fuel injector cleaner, new spark plugs, new spark plug wires, cap & rotor, checked my air intake, took out the fuel pump(filter looked fine), today i finally brought it to a 3 different shops and no one can get an trouble code off the car, my check engine light is on, the people who did the testing are saying the computer might be bad, any suggestions???
