Engine Performance problem
1991 Lexus LS 400 V8 Two Wheel Drive Automatic
i have a 1991 Lexus. Car acts like it wants to rev up when I m stopped at a light and when I drive the car it will slow down and wont pick up speed when I give it gas. Sometimes it will pick up speed and slow back down again. It has a new throttle sensor and wires and plugs. The throttle sensor and wires have been on for about a month. Cant figure out the problem, any help would be appreciated.
