thejim42 Posted March 21, 2015 Share Posted March 21, 2015 Well I've had the new truck for about 2 week now and the last couple days I've been driving it, it will randomly dies. Usually when I have my foot on the brake. It stats back up every time but it's starting to do this more often, it has don't when the truck is warm and cold. I've never had this issue before with my other 88 4.0 and I'm not sure where to even begin to look. It also will idle extremely high sometimes when I start it back up. Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
WiscoXJ Posted March 21, 2015 Share Posted March 21, 2015 Check the map sensor and your grounds Link to comment Share on other sites More sharing options...
thug3 Posted March 21, 2015 Share Posted March 21, 2015 Maybe the crank position sensor. Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted March 22, 2015 Share Posted March 22, 2015 Auto or manual? Link to comment Share on other sites More sharing options...
87MJTIM Posted March 22, 2015 Share Posted March 22, 2015 ballast resistor going bad? If it overheats it shuts of power to the fuel pump. Try by passing the BR. Link to comment Share on other sites More sharing options...
thejim42 Posted March 22, 2015 Author Share Posted March 22, 2015 It's a 5 speed. And I thought about the BR but it only happens when I'm slowing down and don't have my foot on the gas. It didn't happen at all today and I drove all over the place Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted March 23, 2015 Share Posted March 23, 2015 The problem you are experiencing is identical to mine in almost every way. My problem turned out to be a failing TPS sensor, but before you go replacing anything do this. The next time you start your truck and it is idling normally, (850 rpm or so) pop the hood and disconnect the IAC valve. Then drive the truck like that for a day or so. If the stalling/high idle after restart goes away replace the TPS. I would also take the time to thoroughly clean the IAC and throttle body.
