Losses power after running for a couple of minutes
Looking for help. I have a 2000 Grand Cherokee with 4.0 it starts ok after a couple of minutes it losses power. You try to go from a light and it does want to go. I have to push on the gas pedal much harder then normal. It will only run bad for a couple of minutes then run good. I had it in the driveway and got it to do it and at a idle it sounded like it was having a tough time sucking air in so I changed the idle air valve, then throttle position sensor,air & water temp sensors it is not throwing any codes. Any help would be appreciated!
