Engine Performance problem
1994 Ford Explorer 6 cyl Four Wheel Drive Automatic 200000 miles
The engine starts & idles fine. When the accelerator is depressed, the engine 'bogs down' - even under no load. If you 'pump' the accelerator quickly, engine speed can go to about 3000 RPM.
i installed new wires, and a new air filter. Plugs are less than a year old. This problem has gotten progressively worse.
i'm thinking a vacuum leak.
