Hey guys glad to be part of the forum ! I have a 2003 3500 ram with 5.7 hemi have had issues for last 6 months ! Had code for throttle position sensor changed throttle body done relearn with no luck ! Tried changing few other things that I seen on other forums with no solution still! Now as soon as I start truck it goes full throttle then idles up and down and dies ! Seen another thread that said they solved their problem and it was valve spring broke ! Any help would be greatly appreciated if not the truck is gone
