2003 Taurus no power HELP!
I have an issue where the car has no power and would not go faster than 10MPH on a hill. Its a 2003 with 3.0L "U" engine with 196,000 miles. I replaced the fuel filter which was very dirty evidenced by the fuel that came out. I also had a CEL. Found code for cam position sensor and replaced that. Here is a recap of all I did. Spark plugs changed six months ago, ignition coil replaced, spark plug wires replaced, Fuel filter, fuel pump and filter replaced. No foreign debris in tank. Dropped exhaust and ran car, still the same. Removed exhaust Y pipe and knocked out catalyst. While cat was down ran engine, still the same. Car idles fine no issues, rev the car up and it wont go past 4000 RPM, engine sounds muffled with no balls at all. I replaced the cam synchronizer. It cost me 193 with tax. NO DIFFERENCE. I also noticed that the engine has little vacuum. I can feel when I back down the driveway that I have no brake assist. Pull a vacuum hose at idle and it feels like nothing. The engine idles fine no knocks, no ticking, doesnt burn oil, no smoke has no CEL. Cant figure this thing out.
