Question about Cars & Trucks
When Jeep Cherokee 2001 is in drive but break position I hear a click under the front right part of my hood. Then the RPM's throttle slightly for about 2 seconds. This repeats about every ten seconds. Any thoughts on what this could be. This also occurs while driving.
Its hard to say is your ac compressor kicking on i need more details on where the clicking is coming from ac compressor is a guess due to it raising rpms when turned on and makes clicking noise turning on and off

Testimonial: "Hi All, Jeep Cherokee Sport 4.0L 2001- 125k Miles. A few months back my Jeep started "Revving Up" every 7 seconds when the AC was engaged. I would hear a click in the front of the jeep, if looking head on- The click came from the left. Most recently a family member took my Jeep to a repair shop and the owner mentioned there was "Gunk" forcing the car to exert more power to engage when the AC was on. He cleared the gunk and also mentioned that the car works great but may have a tranmission valve problem down the road. But for now its all fine. 24 hours later the Jeep died mid drive. Jeep would start and then die after a few seconds. Other times it would start and I could drive it for a minute and then it would die. We took the jeep back in and now they are telling me the computer is pointing to a problem with the transmission and will cost 1700 to fix. A lot is uncertain at this point. I would also like to point out that prior to the initial trip to the garage regarding the "revving" issue, I had this garage look over the jeep and fix any critical issues. They initially had not mentioned anything wrong with the transmission and this jeep has never had those issues or broken down. Thoughts??? The first garage trip resulted in the replacement of the exhaust system, scrubbing back brakes and a couple other minor fixes. would love to hear some advice on the matter. You can reach me sirectly at firstname.lastname@example.org Thank you so much, i am in the dark on this one."

SOURCE: S80 engine surge at idle
You could have a bad or contaminated Mass Air Flow (MAF) sensor. You can get a used one online for less then 100. You can also purchase a can of MAF sensor cleaner at a local auto supplies store and clean it. It located right at the air filter housing.

Front drivers side could be a bad cap, lower hose or the radiator itself. You need to look carefully and find the leak source. Steam travels and isn't a good indication of where the actual leak is coolant will run down and take any path it can to reach the ground. Therefore, you need to follow it back to where it is coming from, then deal with it. Your water pump can also leak and run down the lower hose. there is a small hole in the pump behind the pulley. If you see coolant coming from there the pump needs to be replaced. Sealers will not work on hoses or pump leaks so don't bother using them for that.
Good luck...don't forget this is free, so rate answers!
I will answer follow-up questions too!
