I have a 98 ford mustang that i bought 3 months ago its a gt, i been having loss of power issues, they have got worse with no check engine light. I took to mechanic and the said it was fuel pump we replaced that the fuel filter plugs wires and the throttle position sensor, still the same i cant even spin the tires most of the time. Sometime its worse than others. It idles fine and runs perfect if i baby it. Soon as i step on it the power is gone well alot less then b4. I seen a post asking if someone with similar problem washed engine cause i did . Thanks for the help
