Hey y'all, I'm new here, but wanted to put in my 2 cents in this topic. Background: I own three 2007 Dodge Nitro's. All 3 have over 200k on them. All 3 are used to deliver mail and packages (my wife, my son and me all work for the postal service). As such, we all drive about 5 hours a day and turn our Nitro's on and off at least 30 times a day. Once they warm up, they are all vulnerable to this hanging start issue. I have been replacing thing on the wife's Nitro to try and overcome this issue. I have currently installed new spark plugs, new coils, a new throttle body, PCV valve and crankshaft position sensor. None of these things has fixed the issue. I guess the next thing to try will be a new TIPM module.
