M42 engine sputtering at low revs

[Gonzo318is]

This just started happening today on the way in to work driving in stop and go traffic. When starting out in the low RPM range the car sputters and then kinda launches forward and drives fine.

Here's what's been replaced within the last year: spark plugs, fuel filter, air filter, and regular oil changes. It is due for an oil change but I know that's not the problem. Car has just over 156K on the clock.

Any ideas? TIA.

Survey says: Vacuum lines


Specifically the one that connects to the bottom of the intake boot between the AFM and throttle body

So I need to replace the vacuum lines? Anyone know the size needed?

make sure they are all present or connected first.
