2007 Dakota idle issue #592562 01/24/10 11:44 AM 01/24/10 11:44 AM

It never stalls, and this symptom only last for a few seconds. I have tried changing the plugs (it needed it, anyway), and have added fuel system cleaner (Seafoam), but to no avail. This is a hit and miss situation, and it never sets a CEL. I have had it to a dealer, but it doesn't happen then, so they tell me they can't help unless the issue duplicates itself. This a 4.7L HO, 4X4 Quad Cab, with 35,000 miles. Any help will be greatly appreciated!

70duster340 OP pro stock 7 Joined: Jan 2003 Posts: 1,443	I know I don't know my way around the 4.7L engine, but the only thing I could locate with 2 screws holding it in was the throttle position sensor, which was behind the throttle body. Can anybody offer a pic or something similar to assist???

Only 1 screw holding it in, but the rubber seals were really holding that thing in!!! Took a lot of tugging to get it out. Cleaned it up with throttle body cleaner, and cleaned up the throttle body around the butterfly valve, too. Seems to idle much better, but only time will tell about the dropping rpm issue, as it was only a sporadic thing. So far, so good!
