Re: Fuel puddling?
So where would be a good place to send the injectors to get cleaned?

Re: Fuel puddling?
the injector squirts gas when the blades are closed the vaccum sucks the gas past the narrow opening helping it to atomize.
key on the injectors give a squirt do the injectors drip? remove air cleaner run truck then place a piece of paper you see on paper if their dripping how does the truck run at idle if it does not sputter i dont beleive there bad you can also use a dialback timing timing to shine at the injector spray pattern this is where you will see a bad injector the pattern will not appears as a cone and the gas will stop then restart spraying |
