2001 Dodge Caravan Repair Question
My Grand Caravan is dumpping to much fuel and is flooding the plugs
Chrysler buys their injectors from Bosch in flow-matched sets and has extremely little trouble with them. Even if one were to stick open, that wouldn't affect the other cylinders.
A problem with the MAP sensor is more likely. The place to start is by viewing live data on a scanner to see what the Engine Computer sees. Based on oxygen sensor readings, the Engine Computer can only add or subtract about 10 percent fuel from the pre-programmed values. If you're getting more fuel than that in all the cylinders, you might check the vacuum hose to the fuel pressure regulator to see if it's leaking raw fuel into the intake manifold. That is real common on GM vehicles, but I've only read about that once on a Chrysler product.
