My 2001 durango has been doing the same thing, idle up and down and engine surges. It does not matter if it is in gear or park. It does not matter if the A/C is on or off. Just had it at the dealership, idle replaced, throttle cleaned. Two days later its back surging and it hesitates when driving and my engine light came on this evening. Any suggestions. HELP!


7/21/06 Dealership replaced the throttle position sensor. It idles normal and no heistation. the check engine lite was intermittent, the dealership said it was considered a "soft code" so it never showed during diagnostics. The code showed up under P0121. OF course the throttle was cleaned out prior, so maybe combined it will not happen. Durango running great!
