testing/cleaning the injectors
How do I know if my injectors are working properly or not? Can I do this?
Detach the injectors from the engine heads, but leave them attached to the fuel rail. Then unplug the wire connectors and apply a 12V electricity to the injectors. Will that trigger the injectors to spay? (so I can see if they are working)
The problem I have on my CLK430 is a slight misfire at idle. The car runs fine, good power and 20+ mpg. I have changed the plugs, the wires, cleaned the MAF and the throttle body. I'm thinking of removing the entire intake manifold and clean the inside and the injectors.
