Glad you found the actual problem instead of just throwing silly wasted parts at it.

So much for the “ONLY” solution........

The main reason I won’t go to the stealerships is for exactly that reason, there’s no THINKING about the problem and finding the solution, it’s just throwing parts at it because a book or computer said to do that.

Thankfully the only place where such foolishness does NOT exist is in aviation, which given the price of parts is a VERY good thing.

According to the description the OP made, Heavy acceleration, The problem was the vacuum was used up......

And yet the OP’s post actually said;

It actually seems to be doing it now under low throttle steady state conditions as well. Obviously a vacuum issue but I'm not finding any obvious leaks.

BTW, my problem stealerships is NOT ‘trust’, it’s the SA and guys in the shop who just throw parts at things because they walk up to the vehicle with a preconceived ‘knowledge’ of what the problem MUST be instead of actually diagnosing the problem and fixing THAT.

In this case a 12 volt electric vacuum pump would have done ZERO unless it happened to be spliced in where the leak was by complete fluke.

There’s no savings in doing a job ‘fast’ if the problem isn’t fixed or an expensive ‘repair’ that was NOT needed is done instead of the repair.

I found my vacuum leak in about ONE minute using a propane bottle, my repair also ‘cost’ me about 2 feet of rubber vacuum tube, maybe a dollar.

Can you sell and install a 12 volt vacuum pump for ONE dollar?
