Greetings! I bought a '94 Ford XLT 4x4. It has 125,000 miles. Got on the freeway, accelerating normally, had a hard time pushing past 65. When I hit a slight decline, I got to about 76. But when going back uphill, I went back down to 65 and couldn't get past it no mater how much I pushed on the gas petal. When I pushed it all the way to the floor the RPMs went up to 3 then dropped under 2 and I started to slow down dramatically. Almost as if the engine turned off. I released the gas and coasted for about 5 seconds then eased the gas. I started to speed up but nothing past 60, until I started driving downhill at a slight decline.
What do you think the problem is, and what is causing it? Nice site : -)
