ok guys,
apparently i have leaking injectors(or at least one) on the old girl...
upon inspection i have a "WET" spot on my passenger valve cover, not oil or blowby but a clear wet looking spot right near one of the middle injectors

my idle has gotten progressively worse over last month, as well as my gas mileage and idle quality.....

im going to install a set of reman injectors with the updated 4 port design, i have a choice between 19lb and/or 24lb, same price for either, and im planning on mild upgrades in the future.... decent weekender cam, MAF swap, etc.... would the 19's be ok or do i need to go higher?.....what if any differences would i see now?? right now im SD

also plan on swapping to O sensor for a new one, i have already gutted the cat, fresh plugs and maybe fresh wires as well....see sig for ignition info...

my previous 16/23mpg has dropped to around 10/15 at the moment, so i definitely am having issues with something.....

does anyone have any other ideas about what might be causing my problems ??
how hard is it to swap the injectors? any special tools needed?

im assuming now is a good time to swap in a new pressure regulator as well, will i need to do anything with the fuel rail ??

thanks...i have some bay time coming to me at a buddies garage so i will be looking to do this next week some time

 

forgot to add, when inspecting the injector areas i noticed that the pcv valve was pushed out of the grommet in the valve cover....what would cause this? is it/could it be something related to the bad injectors ?

 

You to stay with 19lb injectors.
The 24lb injectors are for the 460 engine with a different firmware program in the PCM computer.
