94 Caravan Cherry Manafold

3.0 mamfold gets cherry red after running about 5 minutes. Head gaskets
were replaced but the heds were not rebuilt. What would cause the engine
to shoot flames past the valves?

 

FUEL FUEL AND MORE FUEL. Is the check engine lite on? is the vehicle running
bad???/
Black smoke from the tail pipe?

Check engine light is not on and not codes are flashing. It rung just
below 2000 rpms wich i way to high and it"s not smoking

 

Don't 'cha just love those 3.0 mitsubishi engines??? NOT!

 

look at the converter and see if it's red too

 

The converter is not red and we took it off to see if it was blocked and
that"s when we noticed flames coing out of the manafold

 

You got to take this into a dealer and have them hook a scantool to the
engine computer and run the engine and look at the readouts the scantool
is telling them. This is an EFI engine so something is telling the computer
to
greatly richen the mixture. Somewhere a sensor has gone wrong and the
computer can't detect it.

If you are looking at this at nite after you just come off a drive under
load you will see it may be red. And if you take the manifold off while
the engine is running you will also see flames coming out of the engine.
Thats normal. Other then the that how does the vehicle run?
