I have a 2000 Ranger XLT with 87000 miles on it. My truck was recently involved in a minor accident. It has since been repaired. It ran fine before this. When I start my truck and place it in drive and take my foot off the brake, it doesnt roll foward slowly like a vehicle normally should. When driving it seems like its taking too much power to go as fast as I am. I have checked my E-brake and its not on/stuck. Also when I drive for 10+ minutes and I get out I smell something like its burning. I have checked all fluids and all are full, although I do not know how to check the oil to see if its good/bad. However after I have been driving my truck for a little bit it wil roll foward after removing my foot from the brake while in drive. It has the same problems in R/1/2/D. It recently sat for 3 months in Alaska, with tempatures as low as -25. I have also burned almost 1/2 a tank of gas on 65 miles. Any ideas, or anything I could check myself?
