HI I have a 2000 Ram 1500 5.2 Litre 98,000 miles automatic. when I am driving it I get what sounds like backfire though the intake and I get a loss of power. It feels as if the ignition is cutting off and then turning back-on or feels like its running out of gas.

Also if I am sitting at a light for a long time I start hear what sounds like a vacum leak and there is a rough idle.

any help would be great thanks

 

time to replace the cat. i beleive there is a recall on that year. also the 02 sensor might be going bad
