    Jumping and Grinding at Low Speed

    I'm getting it on the freeway too though. The city stop issues are annoying. The highway problems are scary. I step on it, nothing happens, then it redlines and makes this awful sound. I don't even know to describe it. It's a grind/whine

    Jumping and Grinding at Low Speed

    It's 2000 XLT with a 4.6 and 160,000 miles. I hooked it up to our MODIS scanner at work and the only code showing is a P1875. All it means is the car reached redline. It has very slow acceleration as it is. You press the gas, nothing nothing nothing, and then all of a sudden the tach flies to...

    Jumping and Grinding at Low Speed

    Hey All, I'm having a lot of slipping in the transmission. I hit the gas and the engine revs and the ride is slow and rough, then all of a sudden something feels like it's grinding, and then it jumps and jolts a few times and we're off. It doesn't feel good in the gas pedal either. It gets...

    Idle Issues with AC on

    Idle Issues with AC on

    Hi Guys, I have been having some idle issues with my 2000 Expo XLT with a 4.6 engine. Just for some background on the car, it was my moms daily driver for the first 10 years of its life. 90% of that was city driving. For the last four years, it has been our commuter car to school for my sister...

    Power loss

    Thanks guys. I knew some of it had to do with age and unavoidable wear but 56 hp just seemed extreme to me. And , FordandPolaris, I will post the new results when I get them. I am taking it to be dynoed next Saturday.

    Power loss

    Hey y'all. I am a high school student in Ca. I am doing a research project and testing hp and torque with standard intake and exhaust and then after with a spectre cold air and thrush glasspack. I had the first dyno done and was shocked by the power loss. I have a 2000 expo xlt with the 4.6...
