Will a bad belt cause my 99 Durango SLT to run rough and drop my fuel to 5 mpg?
My 99 Durango 5.2 SLT 4 X 4 suddenly started running really rough, bogs in the higher gears, and my mpg has dropped to only 5mpg. My AC compressor locked up and chewed off 1/3rd of the belt. I replaced the AC with a pulley bracket. I have yet to replace the belt.
