Ok so my uncle had a bunch of old cars and he gave me his old 97jeep tj 2.5l . Yay....Maybe.I've been fixing it up and cleaning everything up and today I took it for a test drive. I live in a VERY hilly area. We were going around my neighborhood and when we went up this one road in third gear it would not get to even twentymph. We floored it and the rpm didn't seem to even go up. I'm new to all this and was just seeing if this is normal? What should I look into? Thanks
