standard injectors are supposed to be 19lbs for a focus correct? I was looking into injector sizes and i found the grey injectors are `14's? would it hurt to put mustang 19lb injectors?

why would you want to do that if the stock injectors are the same size? get some 60 pounders, there easier to tune with

well my wondering is that i may have bad injectors bc #4 cly is running rough and the plug is wet as if its getting to much fuel. i have a couple sets of mustang 19# injectors but i was looking up the different injector colors and it says gray(the ones installed on my car) are 14# inj. the ones i have from mustang are orange tops and 19#'s is there a problem using the mustang ones?

oh, i always heard that stock was 19#, i just heard that from some people. im sure you could get them to work. i know some injectors have to have an adapter to work.

come to think about it i have cel's that say either cyl#1 or #4 misfires. maybe this is similar to your prob. i have changed everything i can think of except injectors and ignition coil.

well i changed to the mustang injectors its better but #4 is still not right....i pulled #4 wire and it cranked right up. i pulled number 2 and 3 and it wouldnt crank with just 1 and 4. i pulled #1 it cranked but ran really rough.

seafoam? by the way have you disabled your egr? that can make your car run crappy at mid rpm's at anything less than WOT
