Replacing my injector pump - question?

[JERMCK]

I took my truck in for service on Tues. - asked the tech to check out why my idle was ocillating and I showed him the post from D-max Man about the RPCV sticking - tech called me back and advised they are replacing pump and my truck will be ready on Thurs. - Called today and they told me they had opened a TAN case with GM and it will not be ready until next Monday. What's going on?

I think you mean a TAC case, and they have to do the offical verification before they replace the pump.
