A couple weeks ago, my Dakota started to idle at 2000 RPM. I waited 3 days to take it into a shop and it was idling at normal speed. I took it in anyway thinking they may be able to figure out why it did that. No such luck. I took it home and the next day it made a hissing noise when I started it up. (It has done this at every start since). It seems like I am getting too many RPM in the lower gears, but no more than 2500 rpms in the higher gears. I have no power getting up hills at 60 MPH, in fact, I slow down. I have to down shift to even get up to hwy speed and the rpm's shoot to 4000 which is not normal in that truck. What could cause this and how can I fix it?
have the same problem?
