Default Another 42# injector question.....

I have just installed a 7# pulley (P1SC) and tried to install 42# svo injectors. When I was done my car felt as if there was a big vacuum leak; I even sprayed carb cleaner on the injectors and the idel went back to normal for a few seconds. Can you put 42#er's in and it run some what right? Or is it a must to immediately tune your computer? Any help would be great.

I did the same thing, The car will run for about 2 minutes then the plugs will get fouled up and it wont run anymore.

You have to tune it imediately!!!

look at it this way....our stock injectors are 26/28# at 58psi of fuel pressure. The svo42# are rated at like 43psi of fp (yes I could be wrong about the exact figure) At 58 psi, the 42#ers are more like 49# injectors. A SIGNIFICANT increase over stock. You cannot just throw them in and drive. a MAFT may make it driveable but it will still suck until you get it tuned

I've read the Ford SVO 42#'ers are flow tested at 39.1 PSI instead of the 43.5 standard.

Can anyone point me to a reference that settles this question for me?

Thanks!

Anyway, cablebandit's point is definitely right-on, in any case. You gotta tune for those injectors!
