have the same thing happening to my Grnd Cherokee V6 2000 Laredo. It only happens when i'm going uphill in 5th gear. It sounds like a ticking noise. I took it to the dealership, they pulled the sparkplugs and said it was ok. They then said that it need a "decarboning". That was a bad answer, he didn't know i did that two weeks ago. It's not enough to have it record on the computer thing he test drove around with. He said it's not going to hurt the car, but it really makes me feel like not driving a little hard now.
I would say it's the same sound that happens if you're in 5th gear going up a hill in a car, when you really should be in 3rd. Like it doesn't have enough power. But these things are sopposed to be able to pull some heavy weight behind them!
any suggestions would help. Probably they didn't replace the spark plugs right, and the dealership is just trying not to repair anything. It was looked at in woodbridge, Hendricks Jeep. Everytime I go in there, they say there's a leak. Actually, they said there was a leak last time in my transfer case, and I made them fix it. They forgot that they fixed that a month ago as well! But is was almost a hassle to get them to do that!
