Why does my Voyager keep stalling after plenum removal?

Answer by  PatW (40)

Main cause is most likely a vacuum leak, either from a vacuum hose left off, or from the plenum gasket itself misaligned Use a can of carburetor spray to isolate leaks. Spray along all gaskets, listening for an RPM increase. When the RPM's go up, you have found your leak.

If the plenum was removed there could be several things that went wrong. First, a gasket could have shifted and isn't sealed right, confusing the computer. One of the many sensors and controls could be unplugged or wires switched - though most are fool proof. Carbon could have gotten loose and is plugging the EGR or MAF sensors.

Chances are the plenum is not seating properly and sucking in extra air. check bolts for tightness or a bad gasket.

IF the only thing done to the engine before the stalling was removing the plenum then that probably is what is causing the stalling issue. I would suspect that you have some type of vacuum leak. You either have a bad or damaged seal allowing air to leak into the intake. Look around the intake and check for leaks.

This may be caused by dirt or other contaminants from when the old plenum was removed. Take the plenum back off and verify the unit is clean.

You have a air leak. You probably didnt tighten the intake bolts to specs. retorque bolts and see if it works.

Chrysler started using the Mitsubishi 3. 0 liter V6 engine in late 1987,they had no V6 of their own ,nothing between their modern four-cylinders and their aging V8s.
