01 engine surge

[chrisc]

i just bought an 01 duramax 3500 and im getting a little bit of engine surge when it idols. im figuring this is prob a bad injector missing during the cycle? if anybody agrees with that can you tell me where might be the cheapest place to get replacements? or if you think it may be aomething else causing it.

Most likely the CP3 regulator.

x2 on FPR. Least expensive I found was Huckstorf Diesel, unless a vendor here can give you a better deal.

An excellent DIY: Dmax Replacing the FCA a.k.a. FPR - Diesel Bombers

if it is the cp3 regulator, will that cause it to fail or is it a major deal? im new to this duramax stuff i ve just converted fro ma dodge man.
