Check the coolant level. Not just the bottle but in the radiator too. The 3400 motor is known for leaking coolant at the intake manifold.
My 1999 Pontiac Montana would seem to "skip a beat" while driving. It then started stalling and restarting, all while driving at highway speeds. My mechanic found that an electrical cable that carried an engine sensor signal was leaning against a hot part of the engine. The cable insulation had melted or worn through, causing intermittent shorts. The shorts confused the engine computer, which then stalled the engine. He simply rerouted the cable and all was fine after that.
Pontiac Montana wheels may fit a Pontiac Vibe, but it depends on specific factors such as the wheel size, bolt pattern, and offset. The Pontiac Vibe typically has a 5x100 mm bolt pattern, while the Montana may have different specifications. It's essential to check the compatibility of the wheel dimensions and consult a professional or reference a compatibility guide before making a decision.
A 2001 Pontiac Montana may cut out while driving due to several potential issues, such as a failing fuel pump, which can disrupt fuel flow to the engine. Electrical problems, like a faulty ignition coil or a malfunctioning crankshaft position sensor, can also cause the engine to stall. Additionally, clogged air filters or fuel injectors may hinder performance and lead to stalling. Regular maintenance and diagnostics can help identify the exact cause.
If your 1994 Pontiac Trans Am randomly stalls out while driving, you may have clogged fuel injectors or a bad distributor. Check the distributor first, as this is the easiest to replace.
crankshaft position censor
A 2002 Pontiac Montana may stall while driving due to several potential issues, including fuel delivery problems, such as a clogged fuel filter or failing fuel pump, which can restrict fuel flow to the engine. Electrical issues, such as a faulty ignition coil or malfunctioning sensors (like the crankshaft or camshaft position sensors), can also lead to stalling. Additionally, problems with the air intake system, such as a dirty mass airflow sensor, might affect engine performance. Regular maintenance and diagnostics can help identify the specific cause.
If you want to turn off the running lights off try to engage the emergency brakes. I have a 2000 Montana and that works.
probably fuel filter or a simple tune up
probably a bad camshaft sensor.
try changing the throttle position sensor
There are a few reasons why a Pontiac 3.4 liter engine may die while driving. The battery cables may of come undone, a spark plug may need changed, or the fuel pump could of stopped working.
First guess would be the pick up coil in the distributor
