Bigl62 Posted March 9, 2018 Share Posted March 9, 2018 Having what could be related issues. Truck just died while travelling, roll to a stop, check for codes and there’s nothing. Turn the key and the truck starts and runs normal. This has happened twice. Then today when bobtailing I had a sluggish throttle/turbo. Then after shutting truck off and restarting it now seems normal again. The truck is a 2014 with 760,000 Kim’s on it.

Mackpro Posted March 12, 2018 Share Posted March 12, 2018 Always start with the battery connections then on to the starter then the firewall pass throughs. Load test each battery separately. Low voltage causes weird problems with the MP engines Quote Link to comment https://www.bigmacktrucks.com/topic/52766-mp8-throttle-response/#findComment-393958 Share on other sites More sharing options...
