Stumbling on Deceleration
Hi
Just finished changing the motor in my 97 3500 4x4 standard.Everything went good.The doner motor came from a 97 2500, i replaced the intake with the original non egr one.Both had the same inj pump.
I now have a hesitation/stumble when i decelerate.This happens when driving and when revving in neutral.So far there are no codes being thrown.
Anyone come across this before?
Thanks Thomas
